The TLE8082ES implements following resets:
•
•
Power on reset
Operation reset:
-
-
-
external reset (NRIO)
V5VI undervoltage reset
watchdog reset
4.2.1
Power On reset
Aꢀer an internal and external V5VI supply ramp up, a power on reset (POR) is performed. The pin NRIO is kept
low for Power On reset time.
The status of the device aꢀer a POR is described in Chapter 4.1.4.
4.2.2
External reset (NRIO)
The pin NRIO is an input/output pin. The output consists of an open drain pull down transistor. The pull down
transistor is supplied by the pin V5VI.
An external reset (NRIO externally pulled to low) can only be detected if the pin is internally not pulled low e.g.
in error state (see Operation states).
An input filter for the low level detection at the pin NRIO is implemented to suppress disturbances. The filter
time is NRIO input filter time. If an external reset is detected, the bit NRIORES in register DIAG0 is set. The bit is
cleared aꢀer an SPI readout.
4.2.3
V5VI undervoltage reset
If an undervoltage according to V5VI Undervoltage monitoring (see Chapter 5.2) is detected, the pin NRIO
is switched to low. Aꢀer recovery, the pin NRIO is kept low for Operation reset time.
The device status is changed according to the definition in Operation states (see Chapter 4.1).
4.2.4
Watchdog reset function
The watchdog reset is generated by the watchdog (see Chapter 6) and bit WDRES in register DIAG0 is set. Aꢀer
readout of DIAG0 the bit WDRES is reset. The pin NRIO is kept low for Operation reset time.
The status of the device is changed according to the Operation states (see Chapter 4.1).
4.3
Key detection
The TLE8082ES implements a voltage detection function at the pin KEY.
An "ON" is detected with a voltage at pin KEY higher than Key On detection threshold for a time longer than
Key detection filter time. The TLE8082ES starts working according to the description in Operation states (see
Chapter 4.1).
An "OFF" is detected with a voltage at pin KEY lower than Key On detection threshold for a time longer than
Key detection filter time. The TLE8082ES reacts according to the Operation states (see Chapter 4.1).
For noise suppression, a Key On detection hysteresis is implemented. The key on detection status is indicated
by the bit KEY in register DIAG0.

Power supply and voltage monitoring function
5.1
Supply functions
The TLE8082ES implements:
•
•
•
•
one internal charge pump
one pre-regulator controlling an external n-channel MOSFET
one 5 V sensor supply with reverse supply protection
one 5 V communication supply
5.1.1
V5VI supply input
The V5VI supply input is used as reference voltage for the 5 V sensor and 5 V communication supply.
Additionally, it supplies the SPI output buffer and power stage gate drivers.
The 5 V main supply of the electronic control unit (ECU) has to be connected to the pin V5VI.
5.1.2
Charge pump
An internal charge pump is implemented for low drop operation. An external capacitor at CP pin must be
connected to AGND.
5.1.3
6.5V Pre-regulator with external MOSFET
The pre-regulator regulates the voltage at pin V6VI to Pre-regulator output voltage via the gate voltage of
an external n-channel MOSFET. In normal operation, the maximum output level of pin VG is defined by Pre-
regulator voltage drop VS to VG - normal operation and Pre-regulator delta voltage VG to VS - low battery.
The drain of the external MOSFET and the pin VS are connected to the same supply node, normally battery
supply.
The function of the pre-regulator is verified with Infineon MOSFET IPD30N06S2L-23.
For stable operation and ripple reduction capacitors are recommended at pin V6VI, pin VG, and pin CP.
5.1.4
5 V Sensor supply
The output T5V of the 5 V sensor supply follows the voltage level at pin V5VI. The sensor supply is supplied out
of pin V6VI.
The output is protected against overload (e.g short to GND) and overtemperature. In case of an overcurrent, the
output current is limited and the diagnosis bit is set. The diagnosis bit is cleared with a readout of register
DIAG0 if no overcurrent is present anymore.
The output is protected against reverse supply to pin V6VI.
The 5 V sensor supply is designed for low battery operation (see Sensor supply low drop resistance).
The 5 V sensor supply can be deactivated through SPI configuration of bit COM5VEN in the CONFIG register.
A capacitor at the pin T5V is recommended for stable operation and ripple reduction.

5 V Communication supply
The output COM5V of the 5 V communication supply follows the voltage level at pin V5VI. The communication
supply is supplied out of pin V6VI.
The output is protected against overload (e.g short to GND) and overtemperature. In case of an overcurrent, the
output current is limited and the diagnosis bit is set. The diagnosis bit is cleared with a readout of register
DIAG0 if no overcurrent is present anymore.
The 5 V communication supply is designed for low battery operation (see Communication supply low drop
resistance).
The 5 V communication supply can be deactivated through SPI configuration of bit T5VEN in the CONFIG
register.
A capacitor, at the pin COM5V is recommended for stable operation and ripple reduction.
5.2
Voltage monitoring
The TLE8082ES implements an undervoltage detection and overvoltage detection at pins V5VI, T5V and COM5V.
All undervoltage and overvoltage diagnosis bits are located in the register DIAG0.
The V5VI undervoltage detection monitors the pin V5VI. Two thresholds are implemented, one for rising
voltages and one for falling voltages. For falling voltages the diagnosis bit is set if the voltage level is below
the V5VI Undervoltage detection threshold 2. If the voltage level is above V5VI Undervoltage detection
threshold 1, the diagnosis bit is reset aꢀer an SPI read out. An Undervoltage detection filter time is
implemented. In case of an undervoltage, the V5VI undervoltage reset is triggered (see Chapter 4.2).
The V5VI overvoltage detection monitors the pin V5VI. For voltage levels above V5VI Overvoltage detection
threshold, the diagnosis bit is set. If the voltage level is below the threshold, the diagnosis bit is reset

Watchdog operation and error definition
The watchdog provides two functions to check the microcontroller:
1.
2.
timing check and
controlling of the functional check inside the microcontroller
A correct trigger of the watchdog is confirmed if the timing check and the control of the functional check
inside the microcontroller are passed. This leads to a decrement of the error counter. All other situations are
considered as watchdog errors and lead to an increment of the error counter. The watchdog status is indicated
by the bits EC, WDTO, WDCE and WDERR in the register WD.
Timing check:
The watchdog expects a watchdog command via SPI inside the open window. If the timing of the
microcontroller is too fast, the watchdog detects a watchdog command inside the closed window. In this
case, the watchdog command too early bit WDCE in register WD is set to 1. If the microcontroller timing is too
slow, the watchdog period is expired and the watchdog time out bit WDTO in register WD is set to 1.
Controlling of the internal functional check of the microcontroller:
The microcontroller transmits the status of the internal functional check by setting the watchdog check
command bit WDC in register WD. If the internal functional check of the microcontroller is not ok, the watchdog
error bit WDERR in register WD is set to 1.

Watchdog error counter
The device implements a 3 bits error counter EC located in the register WD. This corresponds to a counting
range from 0D (000B) to 7D (111B).
The actual counter value can be read via SPI.
The status of the error counter EC defines the state of the device.
•
•
Ready state: EC < 5D
Safe state: EC > 4D
A watchdog reset is generated by an overflow of the error counter EC. For more information about the Reset
state of the watchdog, see Chapter 4.1.5.

Power stages
7.1
Outputs 1 to 3 - inductive load drivers
The TLE8082ES implements 3 low-side switches. Output 1 to 3 are intended to drive inductive loads like
injectors, valves or relays. The outputs contain a clamping circuit for freewheeling of inductive loads.
The control of OUT1 can be configured to direct drive with input pin IN1 or SPI control. OUT2 and OUT3 can be
configured to direct drive with input pin IN23 or SPI control. The output configuration can be determined in the
configuration register.
If the pin control is selected, a high level at input pins IN1 and IN23 switches on the respective output (see
Figure 11).
7.2
Output 4 - O2 heater driver
The low-side switch output 4 is intended to drive resistive loads like O2 heaters. The output contains a clamping
circuit for freewheeling of inductive loads, too.
The TLE8082ES provides a current feedback output. The provided sink current at pin CFB4 is proportional to
the current of OUT4. If OUT4 is switched off, CFB4 is in high ohmic state. The output current at pin CFB4 can be
calculated as follows.
I
= g
· I
CFB4
OUT4
CFB4
Equation 1
The control of OUT4 can be configured to direct drive with input pin IN4 or SPI control.
If pin control is selected, a high level at input pin IN4 switches on OUT4 (see Figure 11).
7.3
Protection and diagnosis of low-side output stages
All low-side output stages are protected against overcurrent.
If the current through a power stage is above the Overcurrent detection threshold for a time longer
than Overcurrent switch off filter time, an overcurrent is detected and the affected powerstage is switched
off. Additionally, the according overcurrent bit in register Diag1 is set.
The following conditions must be fulfilled to switch on the powerstages aꢀer an overcurrent event has
occurred:
•
•
•
no overcurrent condition
readout of register Diag1 to reset the diagnosis bit
power stage switch on command (SPI switch-on command or positive edge at pin INx)
All low-side output stages are protected against overtemperature.
If the power stage temperature is above the OUTx overtemperature detection threshold for a time longer
than OUTx overtemperature filter time, an overtemperature is detected and the affected powerstage is
switched off. Additionally, the overtemperature bit in register Diag1 is set. An Overtemperature hysteresis
avoids a premature switch on.
The following conditions must be fulfilled to switch-on the powerstages aꢀer an overtemperature event has
occurred:
•
•
•
no overtemperature condition
readout of register Diag1 to reset the diagnosis bit
switch-on command (SPI switch on command or positive edge at pin INx)
The OUT3 output switching status (ON/OFF) is detected by Diagnosis in off threshold high. The status bit
O3Stat in register Diag0 is "1" with an output voltage below the threshold.

Diagnosis in OFF-state
All low-side output stages provide open load diagnosis in OFF-state.
All low-side output power stages provide a short to GND diagnosis in OFF-state.
A pull-up current source, a pull-down current source and two detection thresholds are implemented for each
output OFF-state diagnosis.
A short to GND in OFF-state is detected if the output voltage level is below the Diagnosis in off threshold
low for a time longer than the specified filter time (Diagnosis in off filter time OUT1 and OUT2, Diagnosis in
off filter time OUT3 and OUT4).
An open load in OFF-state is detected if the output voltage level is between the Diagnosis in off threshold
low and the Diagnosis in off threshold high for a time longer than specified filter time (Diagnosis in off filter
time OUT1 and OUT2, Diagnosis in off filter time OUT3 and OUT4).
In case of an OFF-state diagnosis detection condition, the respective diagnosis bit in register Diag1 is set. The
diagnosis bits are reset aꢀer a readout of register Diag1 if no fault condition is present.

Priority of diagnosis bit setting
The diagnosis bits OxDIA in register DIAG1 are set according to the diagnosis information .
In OFF-state, open load and short to GND diagnosis information are available. In ON-State, overcurrent
protection and short to battery diagnosis information are available.
To avoid conflicts, the setting of the diagnosis bits is performed according to the priorites below:
1.
2.
3.
short to battery (highest priority)
open load
short to GND (lowest priority)
In case of a parallel diagnostic condition, the bit with higher priority is set. The information on the occurrence
of a diagnosis condition with lower priority is lost.
The diagnosis bits are set to the actual diagnosis status of the device by a read command via SPI.

Serial Peripheral Interface (SPI)
The device has a 16 bit Serial Peripheral Interface (SPI). The SPI is a full duplex synchronous serial interface with
3 inputs and 1 output.
CSN: Chip Select Not (low active) input
SCK: SPI Clock input
SI: Slave Input
SO: Slave Output
The data information at SI and SO is synchronous to the SPI clock. The output levels of the SPI pins are related
to pin V5VI.

9.1
Parallel SPI operation together with TLE8080ES
The implementation of the SPI and the definition of the registers (two addresses for CTRL register) enable a
parallel operation of the SPI communication together with the device TLE8080EM.
9.2
SPI mode definition
A communication frame starts with the falling edge at CSN. At the beginning the clock must be "0" according to
timing definition (Figure 16). The data at pin SI is sampled with the falling edge of SCK. The data at pin SO is
shiꢀed with the rising edge of SCK. The communication frame ends with the rising edge at CSN. At that time the
data received via pin SI is executed and stored internally and the result of the request is prepared for the next
communication as output data. A correct communication frame consists of 16 bits and starts with the MSB first.

Data frame
A correct communication consists of 16 bits in one communication frame and the value of the address bits must
refer to an existing register.
All other communication frames are invalid.

SPI send and response scheme
The logical frame dependency is defined as out-of-frame communication where the logical response of the
slave is within the next frame of the master.
