Functional Block Description

Internal Power Supply (PMU)

The internal blocks of the TLE5014 are supplied from several voltage regulators:

•

GMR Voltage Regulator, VRS

Analog Voltage Regulator, VRA

Digital Voltage Regulator, VRD

These regulators are directly connected to the supply voltage VDD.

Oscillator and PLL (Clock)

The digital clock of the TLE5014 is given by the Phase-Locked Loop (PLL), which is fed by an internal oscillator.

SD-ADC

The Sigma-Delta Analog-Digital-Converters (SD-ADC) transform the analog GMR voltages and temperature

voltage into the digital domain.

Digital Signal Processing Unit ISM_ALG

The Digital Signal Processing Unit ISM_ALG contains the:

•

Intelligent State Machine (ISM), which does error compensation of offset, offset temperature drift,

amplitude synchronicity and orthogonality of the raw signals from the GMR bridges.

COordinate Rotation DIgital Computer (CORDIC), which contains the trigonometric function for angle

calculation

•

Functional Description

Digital Signal Processing Unit ISM_SAF

The Digital Signal Processing Unit ISM_SAF performs the internal safety mechanism and plausibility checks.

Furthermore, a second CORDIC algorithm is implemented in a diverse way as in the ISM_ALG. This is for cross

checking the angle calculation

Interface

The Interface block is used to generate the PWM, SENT and SPC signals

Angle Compare

This digital block compares the angle value calculated by ISM_ALG and ISM_SAF. In case they are not identical,

an error is indicated in the transmitted protocol.

EEPROM

The EEPROM contains the configuration and calibration parameters. A part of the EEPROM can be accessed by

the customer for application specific configuration of the device. Programming of the EEPROM is achieved

with the SICI interface. Programming mode can be accessed directly after power-up of the IC.

1.3

Sensing Principle

The Giant Magneto Resistance (GMR) sensor is implemented using vertical integration. This means that the

GMR-sensitive areas are integrated above the logic part of the TLE5014 device. These GMR elements change

their resistance depending on the direction of the magnetic field.

Four individual GMR elements are connected to one Wheatstone sensor bridge. These GMR elements sense

one of two components of the applied magnetic field:

•

X component, V_x(cosine) or the

Y component, V_y(sine)

With this full-bridge structure the maximum GMR signal is available and temperature effects cancel out each

other.

0°

Figure 1-2 Sensitive bridges of the GMR sensor (not to scale)

Attention: Due to the rotational placement inaccuracy of the sensor IC in the package, the sensors 0° position

may deviate by up to 3° from the package edge direction indicated in Figure 1-2.

In Figure 1-2 the arrows in the resistors represent the magnetic direction which is fixed in the reference layer.

If the external magnetic field is parallel to the direction of the Reference Layer, the resistance is minimal. If

they are anti-parallel, resistance is maximal.

The output signal of each bridge is only unambiguous over 180° between two maxima. Therefore two bridges

are oriented orthogonally to each other to measure 360°.

With the trigonometric function ARCTAN2, the true 360° angle value is calculated out of the raw X and Y signals

from the sensor bridges.

The application circuits in this chapter show the various communication possibilities of the TLE5014. To

improve robustness against electro-magnetic disturbances, a capacitor of 100nF on the supply and a

capacitor with minimum value of Cw = 1nF on the output pin is recommended. These capacitors shall be

placed as close as possible to the corresponding sensor pins.

a Tc of -1300ppm/K. In case a different magnet is used, the individual Tc of this magnet has to be considered

and ensured that the limits are not exceeded. The allowed magnetic field range for the ambient temperature

The delay time describes the time difference of the real angle at the point in time were the SPC/SENT protocol

issues a falling edge (synchronization nibble) and the angle value which is transmitted with this data frame. It

is the “age” of the transmitted angle value in reference to the falling edge of the synchronization pulse.

For PWM interface the reference point in time is the starting edge of the PWM (rising or falling, depending on

protocol setting).

The delay time values given in Table 3-9 include also the internal oscillator variation and jitter.

The delay time variation (or jitter of delay time) describes the statistical variation of this parameter in case

several measurements are done. The delay time t_adelcan be considered as the mean value with the jitter t_deljit

as variation (see Figure 3-5).

Angle Performance

After internal angle calculation, the sensor has a remaining error, as shown in Table 3-11 for an ambient

temperature range up to 85°C and a reduced magnetic field range and in Table 3-12 for the ambient

temperature range up to 125°C and full magnetic operating range. The error value refers to B_Z= 0mT.

The overall angle error represents the relative angle error. This error describes the deviation from the

reference line after zero-angle definition. It is valid for a static magnetic field.

If the magnetic field is rotating during the measurement, an additional propagation error is caused by the

angle delay time (see Table 3-9).

Reset Concept and Fault Monitoring

Some internal and external faults of the device can trigger a reset. During this reset, all output pins are high-

ohmic to avoid any disturbance of other sensors which may be connected together in a bus mode. A reset is

indicated as soon as the sensor is back at operational mode either by a status bit (SPC and SENT protocol) or

with a duty cycle in the diagnostic range (PWM interface). In the case of a periodic reset (sensor toggles

between on and off state) it is avoided that the output toggles with a frequency close to a valid PWM

frequency. In this way it is ensured, that a reset can clearly be distinguished from a valid output signal.

3.6

External & Internal Faults

In case of an occurrence of external or internal faults, as for example overvoltage or undervoltage, the sensor

reacts in a way that these faults are indicated to the customer. This can be either by a status bit (SPC and SENT

protocol) or with a duty cycle in the diagnostic range (PWM interface).

The error signaling (safe state) is defined as:

•

indication of an error (e.g. status bit)

detectable wrong output (e.g. CRC failure)

no output

All errors are indicated as long as they persist, but at least once. After disappearance of the error, the error

indication is also cleared. The error is signaled and communicated to the ECU latest after 5ms from occurrence

of the fault. To achieve this, it has to be ensured that the protocol transmission time is not exceeding 1ms.

Otherwise, the fault tolerant time interval is increased above 5ms.

Final Datasheet

Rev. 1.0

2018-04-04

TLE5014

Specification

Overvoltage, undervoltage

It is ensured, that the sensor provides a valid output value as long as the voltage is within the operating range

or no under- or overvoltage is indicated. At occurrence of an undervoltage, the sensor performs a reset. The

implemented undervoltage comparator at V_DDdetects an undervoltage at ~4.1V (typ. value). At occurrence of

an overvoltage, the sensor output goes to tristate and no protocol is transmitted. The implemented

overvoltage comparator at V_DDdetects an overvoltage at ~6.5V (typ. value). An overvoltage on the output pin

IFB is detected as soon as the voltage at IFB is more than ~1.5V above V_DD.

Open and Shorts

All pins of the device withstand a short to ground (GND) and a short to V_DD(as long as V_DDis within the operating

range). In case of an open V_DDconnection or an open GND the sensor provides a detectable wrong signal (e.g.

no valid output protocol or duty cycle) which is considered as a safe state.

It is also ensured that a short between two neighboring pins leads to a detectable wrong output signal.

Communication Failures

An external fault can happen where an ongoing communication is interrupted before it is finished correctly. In

such an event, no sensor malfunction or dead-lock will occur.

Device Programming (SICI Interface)

To minimize the wiring in the application and to allow an end of line calibration and configuration of the

device at the customer, the programming interface does not require additional pins or wiring. It is possible to

do the programming on the available output line of the sensor output (SPC, SENT or PWM interface). This

single wire interface is called SICI interface. It is only for programming purpose and not for communication or

read out of angle values during operation. The programming mode can be accessed directly after start-up of

the IC by sending the appropriate command on the output line.

Following parameters can be programmed end of line:

•

Zero angle (angle base)

Rotation direction (clock wise or counter clock wise)

Look-up table (32 points)

Customer ID (112bit individual data)

2018-04-04

TLE5014

Specification

To align the angle output of the sensor with the application specific required zero angle direction this value

can be programmed. All further output angles are in reference to this zero angle.

In case several sensors are connected in a bus mode configuration (SPC interface) each sensor needs to have

an individual address to enable a programming of the devices in the bus configuration. Please refer to

Table 4-5 for details how to assign individual addresses to the sensors.

Look-Up Table

To increase the accuracy of the provided angle value, a look-up table is implemented which allows to

compensate for external angle errors which may be introduced for example by the magnetic circuit. Alignment

tolerances (eccentricity or tilt) may lead to a non-linearity of the output signal which can be compensated

using the implemented look-up table. This look-up table has 32 equidistant points over 360° angle range with

a linear interpolation between the 32 defined values

Further details for programming and configuration of the device can be found in the corresponding user

manual of the TLE5014.

Interfaces

This chapter describes the interfaces of the sensor. Several interfaces are implemented, the active interface is

predefined by Infineon and can not be changed. The available preconfigured devices are described in

Chapter 6. The indicated parameters apply to the full operating range, unless otherwise specified. The typical

values correspond to a supply voltage V_DD= 5.0V and an ambient temperature of T_A= 25°C, unless individually

specified. All other values correspond to -40°C < T_A< 125°C

4.1

Sensor Output Driver

The TLE5014 has an output driver on the pin IFB which can be switched from a push-pull configuration to a

quasi-open drain with active controlled slope.

•

The push-pull configuration is preferred with SENT and PWM interface. It has controlled rising and falling

slopes to reduce EMC emission and provides a controlled and defined pulse length independent of

external circuitry. The push-pull output driver switches between 0V and V_DD. An additional pull-down or

pull-up resistor is recommended to ensure a defined output level at sensor start-up.

•

For the SPC interface the open drain setting with controlled slopes is required. In this configuration, the

TLE5014 has controlled rising and falling slopes but after reaching the HIGH-level, the output is switched

to an open-drain behavior. The HIGH level is then maintained by the external pull-up resistor. It is

necessary, that the sensor releases the output line once reaching the HIGH level so that the master (µ-

Controller) can issue the SPC trigger pulse by pulling the line low.

4.2

Pulse Width Modulation (PWM) Interface

PWM Interface: An uni-directional interface with the angle information coded in the length of a pulse. The

angle value is proportional to the duty cycle of the output frequency.

The duty cycle is calculated as the ratio of the “high” time to the period length. An increasing angle results in

an increased duty cycle, with an angle of 0° having the smallest duty cycle.

up condition with a falling edge (start with a HIGH level), a pull-up resistor instead has to be implemented.

PWM Interface Error Indication

For diagnostic purpose and to indicate internal sensor failures, the output duty cycle of the PWM is limited.

Within this reserved lower and upper duty cycle range, no valid angle information is provided. Instead, this

duty cycle range is used for error indication with defined duty cycles which are clearly separated from the

usable data duty cycle range. The following events are indicated:

•

Error occurred during performing the built-in self test (BIST) after power-up

Occurrence of internal or external fault

Sensor reset occurred

PWM Interface Configuration

The PWM interface parameter can be configured in a wide range. Beside the frequency, it is also possible to

define data duty cycle range and low and high value of the diagnostic duty cycle. It has to be ensured by proper

device configuration that there is no overlap of data duty cycle range and low or high value of diagnostic duty

cycle.

A possible and valid configuration is:

•

Data duty cycle: 12.5% ...87.5%, the 12bit angle value is mapped to this duty cycle

Diagnostic duty cycle, low: 5%; an internal sensor fault is indicated with this duty cycle

Diagnostic duty cycle, high: 95%; an start-up BIST error or sensor reset is indicated with this duty cycle

As the PWM interface is an analog protocol, the rise and fall times, as well as the trigger level for the detection

of the high and low state of the signal have influence on the measured duty cycle. Therefore, an additional

angle error is introduced which varies with the measurement conditions (e.g. Rp, CW, trigger level). This error

contribution is not included in Table 3-11 and Table 3-12.

Short PWM Code (SPC)

The Short PWM Code (SPC) is a synchronized data transmission based on the SENT protocol (Single Edge

Nibble Transmission) defined by SAE J2716. As opposed to SENT, which implies a continuous transmission of

data, the SPC protocol transmits data only after receiving a specific trigger pulse from the microcontroller. The

required length of the trigger pulse depends on the sensor number, which is configurable. Thereby, SPC allows

the operation of up to four sensors on one bus line.

As in SENT, the time between two consecutive falling edges defines the value of a 4-bit nibble, thus

representing numbers between 0 and 15. The transmission time therefore depends on the transmitted data

values. All values are multiples of a unit time frame concept (Table 4-3). A SPC frame consists of the following

nibbles (see Figure 4-2):

•

A trigger pulse from the master (microcontroller), which initiates the data transmission

A synchronization period of 56 UT

A status nibble of 12-27 UT

3 data nibbles of 12-27 UT, transmitting a 12bit angle value

A 4bit rolling counter of 12-27 UT (optional)

A CRC nibble of 12-27 UT

An end pulse to terminate the SPC transmission (12 UT)

The CRC checksum includes the status nibble and the data nibbles and can be used to check the validity of the

decoded data.

The status nibble, which is sent with each SPC data frame, provides an error indication. In case the sensor

detects an error, the corresponding error bit in the status nibble is set. An error is indicated by the

corresponding error bit in the status nibble as long as it persists, but at least once.

SPC bus mode

When the sensor is used in a bus mode with other sensors on a common SPC line, individual addresses have

to be assigned to each sensor for identification. These address is configured in the EEPROM of the device. A

corresponding trigger nibble from the microcontroller can therefore address each individual sensor. The

trigger nibble low time is shown in Table 4-6. Each low time corresponds to an individual sensor address. The

total length of the trigger nibble can be selected to be constant at 90UT (constant trigger length) or variable

according to Table 4-7 (variable trigger length).

Selection of the addresses for SPC interface and bus programming

The SPC protocol allows a bus configuration of up to 4 participants on one output line. To identify the

individual devices and allow a programming in the bus mode, an individual address has to be assigned to each

sensor. The programming interface SICI is using hard-wired addresses (see Table 4-5), whereas the SPC

protocol uses the addresses configured in the corresponding EEPROM of the sensor. For the operation of the

sensor in a SPC bus mode, it is strongly recommended that the hard-wired address is also written into the

EEPROM of the sensor, as all sensors are preconfigured with the default value “ID = 0” (see user manual for

further details).

Master Trigger Pulse Requirements

A SPC transmission is initiated by a master trigger pulse on the output pin. To detect a low-level, the voltage

must be below a threshold V_th. The sensor detects that the output line has been released as soon as V_this

crossed. Figure 4-3 shows the timing definitions for the master pulse. The master low time t_mlowis given in

Table 4-6. The total trigger time t_mtris given in Table 4-7.

After a SPC frame is transmitted, it is necessary to wait for a specified delay time t_{frame,blanking}, before the next

SPC trigger can be issued. This time is defined from the falling edge of the end pulse to the falling edge of the

trigger nibble (see Figure 4-4).

SPC Features

Rolling counter

This 4bit counter counts the number of transmitted frames with rollover back to 0 and increment with each

message. This counter is for verification in the ECU that no frame is missed or that no frame is sent repeatedly

from the sensor. The rolling counter nibble is sent after the 3rd data nibble and before the CRC nibble.

The rolling counter nibble can be disabled, but to meet the safety requirements and target ASIL level of the

application, this is not recommended.

Optional, the rolling counter can be included in the CRC nibble, thus reducing the total number of nibbles and

therefore the total frame length. In this case, the rolling counter is reduced to a 2bit value. Further details can

be found in Chapter 4.3.3

Short Serial Message

The short serial message is an additional option which can be enabled and disabled. The short serial message

provides additional information in a slow channel transmitting a 8bit temperature value, a 16bit word

containing angle base & rotation direction information and a 32bit sensor ID.

In each SPC frame, one bit of information is transmitted. The start of the short serial message is indicated by

a “1” in bit [1] of the status nibble. For the next 15 SPC frames, this bit will contain a “0”. Information is

transmitted in blocks of 16bit with 1 bit per SPC frame in bit [0] of the status nibble.

4 bit message ID

8 bit data

4bit CRC (calculated from message ID and data bits)

The message ID is used for identification of the type of data received. All data are transmitted in the bit [0] of

the status nibble in the order MSB to LSB.

The transmitted information is as follows:

Message -ID 0: 8bit temperature value starting with MSB

Message -ID 1: 8bit of angle base (starting with MSB) address 0x00A0, bit [15:8]

Message -ID 2: 8bit of angle base (starting with MSB-8) address 0x00A0, bit [7:0]

Message -ID 3: 8bit temperature value starting with MSB

Message -ID 4: 8bit of sensor ID1 (starting with MSB) address 0x00F2, bit [15:8]

Message -ID 5: 8bit of sensor ID1 (starting with MSB-8) address 0x00F2, bit [7:0]

Message -ID 6: 8bit of sensor ID2 (starting with MSB) address 0x00F4, bit [15:8]

Message -ID 7: 8bit of sensor ID2 (starting with MSB-8) address 0x00F4, bit [7:0]

Temperature Calculation

The temperature information which is transmitted with the short serial message is an 8-bit value. It has to be

considered as a two-complement ranging from T[LSB] = -128LSB ... +127 LSB

To obtain the temperature value in °C the following calculation has to be performed:

Checksum Nibble Details

The checksum nibble is a 4-bit CRC of the data nibbles including the status nibble. The CRC is calculated using

a polynomial x⁴+x³+x²+1 with a seed value of 0101B. The remainder after the last data nibble is transmitted as

CRC.

Depending on SPC frame configuration, different options for the CRC calculation have to be considered:

Short serial message disabled and rolling counter information as nibble:

the input data for CRC calculation are: STATUS & DATA1 & DATA2 & DATA3 & ROLLING_COUNTER

Rolling counter information is coded in the CRC (no explicit rolling counter nibble):

The two LSBs of the rolling counter information is prepended to "00" and added to the input data of the CRC

calculation (R1 R0 0 0). In this case, the rolling counter has only 2 bits.

Short serial message enabled and rolling counter information transmitted as nibble:

the sensor ID is coded in the CRC: the two bit value of the ID on LSB position is appended to “00” and added to

the input data of the CRC calculation (0 0 ID1 ID0)

Short serial message enabled and the rolling counter information coded in the CRC:

the two bit value of the ID on LSB position is appended to the 2LSB value of the rolling counter on MSB position

and added to the input data of the CRC calculation (R1 R0 ID1 ID0). In this case, the rolling counter has only 2

bits.

SENT data range and error indication

There are two options for the data range and error indication.

•

0°... 360° are mapped to 12bit, i.e. 0... 4095. This information is coded in the three data nibbles. In case of

an internal chip error or a start-up error (BIST error), the status bit [0] of the status nibble is set. An angle

value is transmitted but might not be valid due to the occurred error.

•

0° ... 360° are mapped to 1 ... 4088. In case of an internal sensor error or start-up error (BIST error), the

message “4091” is transmitted and the status bit [0] of the status nibble is set. In case the sensor performs

a reset, the first transmitted status nibble has the status bit [0] set but a valid angle value (within the range

0... 4088) is transmitted with the 3 data nibbles.

SICI Interface

A single wire interface (SICI) which is on the same output pin as the SENT/SPC and PWM output, is

implemented. This interface is used to perform the EEPROM programming with application and customer

specific data (angle base, look-up table, customer-ID). In addition, some chip configuration can be done.

Further details can be found in the corresponding user manual.

End of Line Configuration

Several parameters can be programmed via the single wire interface SICI end of line. No additional

programming pin is required, programming is performed via the output pin. Further details can be found in

the corresponding user manual.

5.1

Angle Base and Rotation Direction

An angle base value can be stored in the EEPROM. The output angle value is then referenced to this angle base.

It is also possible to define the rotation direction, i.e. for a given magnet rotation direction the output angle

value can either be selected to increase or decrease.

5.2

Customer ID

A total storage of 112bits in the EEPROM is reserved for customer specific data (e.g. customer module ID,

etc...). This data can be written via SICI interface. The read-out of the first 32bits of this data can be done with

the short serial message feature during operation as a slow message (only SENT and SPC interface). The

remaining 80bits can only be addressed via SICI and are not asccessible during operation.

5.3

Look-up Table

To increase the sensor performance and angle accuracy, a look-up table with 32 points can optionally be used.

Non-linearity errors coming for example from a misaligned magnetic circuit can thus be compensated. It is

necessary to have an external angle reference for this calibration. The sensor output values at predefined,

precise positions (0°, 11.25°, 22.5°, ...), given by the external reference, have to be determined. These 32 values

are stored in the corresponding EEPROM registers. The sensor performs a linear interpolation between these

reference points for the output value.
