HAL 1002  
Highly Precise Programmable Hall-Effect Switch  
Release Note: Revision bars indicate significant changes to previous version  
1. Introduction  
The HAL1002 is the improved successor of the HAL 1000 Hall-effect switch. The major  
sensor characteristics, the two switching points BON and BOFF , are programmable for  
the application. The sensor can be programmed to be unipolar or latching, sensitive to  
the magnetic north pole or sensitive to the south pole, with normal or with an electrically  
inverted output signal. Several examples are shown in Fig. 3–4 through Fig. 3–7.  
The HAL1002 is based on the HAL83x family and features a temperature-compensated  
Hall plate with chopper offset compensation, an A/D converter, digital signal processing, a  
push-pull output stage, an EEPROM memory with redundancy and Lock function for the  
calibration data, a serial interface for programming the EEPROM, and protection devices  
at all pins. Internal digital signal processing is of great benefit because analog offsets, tem-  
perature shifts, and mechanical stress effects do not degrade the sensor accuracy.  
The HAL1002 is programmable by modulating the supply voltage. No additional pro-  
gramming pin is needed. Programming is simplified through the use of a two-point cali-  
bration. Calibration is accomplished by adjusting the sensor output directly to the input  
signal. Individual adjustment of each sensor during the customer’s manufacturing pro-  
cess is possible. With this calibration procedure, the tolerances of the sensor, the mag-  
net, and the mechanical positioning can be compensated for the final assembly. This  
offers a low-cost alternative for all applications that presently require mechanical adjust-  
ment or other system calibration.  
In addition, the temperature compensation of the Hall-effect Integrated Circuit (IC) can  
be tailored to all common magnetic materials by programming first and second order  
temperature coefficients of the Hall-effect sensor’s sensitivity. This enables operation  
over the full temperature range with constant switching points.  
The calculation of the individual sensor characteristics and the programming of the  
EEPROM memory can easily be done with a PC and the application kit from  
TDK-Micronas.  
The sensor is designed and produced in sub-micron CMOS technology for the use in  
hostile industrial and automotive applications with nominal supply voltage of 5 V in the  
ambient temperature range from 40 °C up to 150 °C.  
The HAL1002 is available in the leaded package TO92UT.

3. Functional Description  
3.1. General Function  
The HAL1002 is a monolithic Integrated Circuit (IC) which provides a digital output sig-  
nal in response to an magnetic input signal. The sensor is based on the HAL83x  
design.  
The Hall plate is sensitive to magnetic north and south polarity. The external magnetic-  
field component perpendicular to the branded side of the package generates a Hall volt-  
age. This voltage is converted to a digital value and processed in the Digital Signal Pro-  
cessing unit (DSP) according to the settings of the EEPROM registers. The function and  
the parameters for the DSP are explained in Section 3.2. on page 9.  
The setting of the LOCK register disables the programming of the EEPROM memory for  
all time. This register cannot be reset.  
As long as the LOCK register is not set, the output characteristic can be adjusted by  
programming the EEPROM registers. The IC is addressed by modulating the supply  
voltage (see Fig. 3–1). After detecting a command, the sensor reads or writes the mem-  
ory and answers with a digital signal on the output pin. The output of the sensor does  
react to a magnetic field during the communication.  
Internal temperature compensation circuitry and the spinning current offset compensation  
enable the operation over the full temperature range with minimal changes of the switching  
points. The circuitry also rejects offset shifts due to mechanical stress from the package.  
The non-volatile memory consists of redundant EEPROM cells. In addition, the HAL1002  
is equipped with devices for overvoltage and reverse-voltage protection at all pins.

3.2. Digital Signal Processing and EEPROM  
Note  
In this section the digital signal processing is described for a linear sensor  
on which the HAL1002 is based.  
The DSP is the main part of the sensor and performs the signal processing. The parame-  
ters for the DSP are stored in the EEPROM registers. The details are shown in Fig. 3–3.  
Terminology:  
SENSITIVITY: name of the register or register value  
Sensitivity: name of the parameter  
EEPROM Registers:  
The EEPROM registers include three groups:  
Group 1 contains the registers for the adaptation of the sensor to the magnetic system:  
MODE for selecting the magnetic-field range and filter frequency, TC and TCSQ for the  
temperature characteristics of the magnetic sensitivity and thereby for the switching points.  
Group 2 contains the registers for defining the switching points: SENSITIVITY, VOQ,  
LOW-LEVEL, and HIGH-LEVEL.  
The comparator compares the processed signal voltage with the reference values Low-  
Level and High-Level.  
The output switches on (low) if the signal voltage is higher than the High-Level, and  
switches off (high) if the signal falls below the Low-Level. Several examples of different  
switching characteristics are shown in Fig. 3–4 to Fig. 3–7.  
– The parameter VOQ (Output Quiescent Voltage) corresponds to the signal voltage at  
B = 0 mT.  
– The parameter Sensitivity defines the magnetic sensitivity:  
VSignal  
Sensitivity =  
B
– The signal voltage can be calculated as follows:  
VSignal Sensitivity B + VOQ  
Therefore, the switching points are programmed by setting the SENSITIVITY, VOQ,  
LOW-LEVEL, and HIGH-LEVEL registers. The available TDK-Micronas software calcu-  
lates the best parameter set respecting the ranges of each register.  
Group 3 contains TDK-Micronas registers and LOCK for the locking of all registers. The  
TDK-Micronas registers are programmed and locked during production and are read-  
only for the customer. These registers are used for oscillator frequency trimming, A/D  
converter offset compensation, and several other special settings.

TC Register  
The temperature dependence of the magnetic sensitivity can be adapted to different  
magnetic materials in order to compensate for the change of the magnetic strength with  
temperature. The adaptation is done by programming the TC (Temperature Coefficient)  
and the TCSQ registers (Quadratic Temperature Coefficient). Thereby, the slope and the  
curvature of the temperature dependence of the magnetic sensitivity can be matched to  
the magnet and the sensor assembly. As a result, the output voltage characteristic can  
be constant over the full temperature range. The sensor can compensate for linear  
temperature coefficients ranging from about 3100 ppm/K up to 1000 ppm/K and  
quadratic coefficients from about 7 ppm/K² to 2 ppm/K².  
The full TC range is separated in the following four groups:

TC (5 bits) and TCSQ (3 bits) have to be selected individually within each of the four  
ranges. For example 0 ppm/k requires TC-Range = 1, TC = 15 and TCSQ = 1. Please

Sensitivity Register  
The SENSITIVITY register contains the parameter for the multiplier in the DSP. Sensitivity  
is programmable between 4 and 4 in steps of 0.00049.  
VOQ Register  
The VOQ register contains the parameter for the adder in the DSP. VOQ is the signal  
voltage without external magnetic field (B = 0 mT, respectively ADC-READOUT = 0)  
and programmable from VSUP up to VSUP. For VSUP = 5 V, the register can be  
changed in steps of 4.9 mV.  
Note  
If VOQ is programmed to a negative voltage, the maximum signal voltage is  
limited to:  
V
Signal max = VOQ + VSUP  
Reference Level Register  
The LOW-LEVEL and HIGH-LEVEL registers contain the reference values of the com-  
parator.  
The Low-Level is programmable between 0 V and VSUP/2. The register can be changed  
in steps of 9.77 mV. The High-Level is programmable between 0 V and VSUP in steps of  
9.77 mV.  
The four parameters Sensitivity, VOQ, Low-Level, and High-Level define the switching  
points BON and BOFF. For calibration in the system environment, a two-point adjustment  
procedure is recommended (see Section 3.3.). The suitable parameter set for each  
sensor can be calculated individually by this procedure.  
GP Register  
This register can be used to store information, like production date or customer serial  
number. TDK-Micronas will store production lot number, wafer number and x,y coordi-  
nates in registers GP1 to GP3. The total register contains four blocks (GP0 to GP3) with  
a length of 13 bits each. The customer can read out this information and store it in his  
production data base for reference or he can store own production information instead.  
Note  
This register is not a guarantee for traceability because readout of registers  
is not possible after locking the IC.  
To read/write this register it is mandatory to read/write all GP register one  
after the other starting with GP0. In case of a writing the registers it neces-  
sary to first write all registers followed by one store sequence at the end.  
Even if only GP0 should be changed all other GP registers must first be  
read and the read out data must be written again to these registers.

LOCK Register  
By setting the LSB of this 2-bit register, all registers will be locked, and the sensor will  
no longer respond to any supply voltage modulation. This bit is active after the first  
power-off and power-on sequence after setting the Lock bit.  
Warning This register cannot be reset!  
ADC-READOUT Register  
This 14-bit register delivers the actual digital value of the applied magnetic field after fil-  
tering but before the signal processing. This register can be read out and is the basis for  
the calibration procedure of the sensor in the system environment.

Note  
The MSB and LSB are reversed compared with all the other registers.  
Please reverse this register after readout.  
Note  
During calibration it is mandatory to set the parameter for OUTPUT MODE  
to 0. The Digital Output register can be read out only in this configuration.  
For other configurations of the OUTPUT MODE the result read back from  
the sensor will be 0. After the calibration the output format can than easily  
be switched to the wanted output mode.

3.3. General Calibration Procedure  
For calibration in the system environment, the application kit from TDK-Micronas is rec-  
ommended. It contains the hardware for the generation of the serial telegram for program-  
ming and the corresponding software for the input or calculation of the register values.  
In this section, the programming of the sensor using this tool is explained. Please refer  
to Section 6. on page 32 for information about programming without this tool.  
For the individual calibration of each sensor in the customer‘s application, a two-point  
adjustment is recommended (see Fig. 3–8 for an example). When using the application  
kit, the calibration can be done in three steps:  
Step 1: Input of the registers which need not be adjusted individually  
The magnetic circuit, the magnetic material with its temperature characteristics, and the  
filter frequency, are given for this application.  
Therefore, the values of the following registers should be identical for all sensors in the  
application.  
– FILTER  
(according to maximum signal frequency)  
The 500 Hz range is recommended for highest accuracy.  
– RANGE  
(according to the maximum magnetic field at the sensor position)  
– TC and TCSQ  
(depends on the material of the magnet and the other temperature dependencies of  
the application)  
Write the appropriate settings into the HAL1002 registers.

Step 2: Initialize DSP  
As the Digital Output register value depends on the setting of SENSITIVITY, VOQ and  
HIGH/LOW LEVEL, these registers have to be initialized with defined values first:  
– VOQINITIAL = 2048  
– SensINITIAL = (see Table 3–7)  
– Low Level = 0  
– High Level = 511

Note  
This step is done by TDK-Micronas’ customer software automatically by  
clicking the Write and Store button.  
Step 3: Calculation of the Sensor Parameters  
Fig. 3–8 shows the typical characteristics for a contactless switch. There is a mechani-  
cal range where the sensor must be switched high and where the sensor must be  
switched low.  
Set the system to the calibration point where the sensor output must be high, and click  
the button “Readout BOFF”. The result is the corresponding digital value.  
Then, set the system to the calibration point where the sensor output must be low, click  
the button “Readout BON” and get the second digital value.  
Now, adjust the hysteresis to the desired value. The hysteresis is the difference  
between the switching points and suppresses oscillation of the output signal. With  
100% hysteresis, the sensor will switch low and high exactly at the calibration points. A  
lower value will adjust the switching points closer together. Fig. 3–8 shows an example  
with 80% hysteresis.  
By clicking the button “calibrate and store”, the software will calculate the corresponding  
parameters for Sensitivity, VOQ, Low-Level, High-Level and stores these values in the  
EEPROM.  
This calibration must be done individually for each sensor.  
The sensor is now calibrated for the customer application. However, the programming  
can be changed again if necessary.

The register values for the following registers are given for all sensors in the application:  
– FILTER  
– RANGE  
– Output Mode  
– TC  
Select the filter frequency: 500 Hz  
Select the magnetic-field range: 30 mT  
Select the output mode: switch (positive polarity)  
For this magnetic material: 0  
– TCSQ  
For this magnetic material: 0  
– TC-Range  
For this magnetic material: 500 to 450 ppm/K  
Enter these values in the software and use the “write and store” command to store  
these values permanently in the registers.

Step 2: Calculation of the sensor parameters  
Set the system to the calibration point where the sensor output must be high and press  
“Readout BOFF”.  
Set the system to the calibration point where the sensor output must be low and press  
“Readout BON”.  
Now, adjust the hysteresis to 80% and click the button “calibrate and store”.  
Step 3: Locking the Sensor  
The last step is activating the Lock function with the “Lock” command. The sensor is now  
locked and does not respond to any programming or reading commands. Please note that  
the Lock function becomes effective after power-down and power-up of the Hall-effect IC.  
Warning The LOCK register cannot be reset!

5.1. Application Circuit  
For EMC protection, it is recommended to connect one ceramic 100 nF capacitor  
between ground and the supply voltage, and between ground and the output pin.  
Please note that during programming, the sensor will be supplied repeatedly with the  
programming voltage of 12.5 V for 100 ms. All components connected to the VSUP line  
at this time must be able to resist this voltage.

5.2. Temperature Compensation  
The relationship between the temperature coefficient of the magnet and the corre-  
sponding TC and TCSQ codes for linear compensation is given in the following table. In  
addition to the linear change of the magnetic field with temperature, the curvature can  
be adjusted as well. For this purpose, other TC and TCSQ combinations are required  
which are not shown in the table. Please contact TDK-Micronas for more detailed infor-  
mation on this higher order temperature compensation.  
The HAL83x and HAL1002 contain the same temperature compensation circuits. If an  
optimal setting for the HAL83x is already available, the same settings may be used for  
the HAL1002.

ature TJ) is higher than the temperature outside the package (ambient temperature TA).  
TJ = TA + T  
At static conditions and continuous operation, the following equation applies:  
T = ISUP VSUP RthJ  
For typical values, use the typical parameters. For worst case calculation, use the max.  
parameters for ISUP and Rth, and the max. value for VSUP from the application.  
For VSUP = 5.5 V, Rth = 235 K/W, and ISUP = 10 mA, the temperature difference  
T = 12.93 K.  
For all sensors, the junction temperature TJ is specified. The maximum ambient temper-  
ature TAmax can be calculated as:  
TAmax = TJmax T

ESD results.

6. Programming  
6.1. Definition of Programming Pulses  
The sensor is addressed by modulating a serial telegram on the supply voltage. The  
sensor answers with a serial telegram on the output pin.  
The bits in the serial telegram have a different bit time for the VSUP-line and the output.  
The bit time for the VSUP-line is defined through the length of the Sync bit at the beginning  
of each telegram. The bit time for the output is defined through the Acknowledge bit.  
A logical “0” is coded as no voltage change within the bit time. A logical “1” is coded as a  
voltage change between 50% and 80% of the bit time. After each bit, a voltage change  
occurs.  
6.2. Definition of the Telegram  
Each telegram starts with the Sync bit (logical 0), 3 bits for the Command (COM), the  
Command Parity bit (CP), 4 bits for the Address (ADR), and the Address Parity bit (AP).  
There are 4 kinds of telegrams:  
– Write a register (see Fig. 6–2)  
After the AP bit, follow 14 Data bits (DAT) and the Data Parity bit (DP). If the telegram  
is valid and the command has been processed, the sensor answers with an Acknowl-  
edge bit (logical 0) on the output.  
– Read a register (see Fig. 6–3)  
After evaluating this command, the sensor answers with the Acknowledge bit, 14 Data  
bits, and the Data Parity bit on the output.  
– Programming the EEPROM cells (see Fig. 6–4)  
After evaluating this command, the sensor answers with the Acknowledge bit. After  
the delay time tw, the supply voltage rises up to the programming voltage.  
– Activate a sensor (see Fig. 6–5)  
If more than one sensor is connected to the supply line, selection can be done by first  
deactivating all sensors. The output of all sensors have to be pulled to ground. With  
an activate pulse on the appropriate output pin, an individual sensor can be selected.  
All following commands will only be accepted from the activated sensor.

6.3. Telegram Codes  
Sync Bit  
Each telegram starts with the Sync bit. This logical “0” pulse defines the exact timing for tp0.  
Command Bits (COM)  
The Command code contains 3 bits and is a binary number. Table 6–2 shows the available  
commands and the corresponding codes for the HAL 1002.  
Command Parity Bit (CP)  
This Command Parity bit is “1” if the number of zeros within the 3 Command bits is  
uneven. The Command Parity bit is “0”, if the number of zeros is even.  
Address Bits (ADR)  
The Address code contains 4 bits and is a binary number. Table 6–3 shows the available  
addresses for the HAL 1002 registers.  
Address Parity Bit (AP)  
This Address Parity bit is “1” if the number of zeros within the 4 Address bits is uneven.  
The Adress Parity bit is “0” if the number of zeros is even.  
Data Bits (DAT)  
The 14 Data bits contain the register information.  
The registers use different number formats for the Data bits. These formats are explained  
in Section 6.4.  
In the Write command, the last bits are valid. If, for example, the TC register (10 bits) is  
written, only the last 10 bits are valid.  
In the Read command, the first bits are valid. If, for example, the TC register (10 bits) is  
read, only the first 10 bits are valid.  
Data Parity Bit (DP)  
This Data Parity bit is “1” if the number of zeros within the binary number is even. The  
Data Parity bit is “0” if the number of zeros is uneven.

Binary Number:  
The most significant bit is given as first, the least significant bit as last digit.  
Example: 101001 represents 41 decimal.  
Signed Binary Number:  
The first digit represents the sign of the following binary number (1 for negative, 0 for  
positive sign).  
Example: 0101001 represents +41 decimal  
1101001 represents 41 decimal  
Two’s-Complement Number:  
The first digit of positive numbers is “0”, the rest of the number is a binary number. Neg-  
ative numbers start with “1”. In order to calculate the absolute value of the number, cal-  
culate the complement of the remaining digits and add “1”.  
Example: 0101001 represents +41 decimal  
1010111 represents 41 decimal

HAL 1002  
6.6. Programming Information  
If the content of any register (except the LOCK register) is to be changed, the desired  
value must first be written into the corresponding RAM register. Before reading out the  
RAM register again, the register value must be permanently stored in the EEPROM.  
Permanently storing a value in the EEPROM is done by first sending an ERASE com-  
mand followed by sending a PROM command. The address within the ERASE and  
PROM commands must be zero. ERASE and PROM act on all registers in parallel.  
If all HAL 1002 registers are to be changed, all writing commands can be sent one after  
the other, followed by sending one ERASE and PROM command at the end.  
During all communication sequences, the customer has to check if the communication  
with the sensor was successful. This means that the acknowledge and the parity bits sent  
by the sensor have to be checked by the customer. If the TDK-Micronas programmer  
board is used, the customer has to check the error flags sent from the programmer board.  
Note  
Note  
For production and qualification tests it is mandatory to set the Lock bit  
after final adjustment and programming of HAL 1002. The Lock function is  
active after the next power-up of the sensor.  
The success of the lock process shall be checked by reading at least one  
sensor register after locking and/or by an analog check of the sensors out-  
put signal.  
Electrostatic discharges (ESD) may disturb the programming pulses.  
Please take precautions against ESD.
