DATA SHEET
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, temperature shifts, and mechanical stress effects do not degrade the sensor accuracy.
The HAL1002 is programmable by modulating the supply voltage. No additional programming pin is needed. Programming is simplified through the use of a two-point calibration. Calibration is accomplished by adjusting the sensor output directly to the input
signal. Individual adjustment of each sensor during the customer’s manufacturing process is possible. With this calibration procedure, the tolerances of the sensor, the magnet, and the mechanical positioning can be compensated for the final assembly. This
offers a low-cost alternative for all applications that presently require mechanical adjustment 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 signal 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 magneticfield component perpendicular to the branded side of the package generates a Hall voltage. This voltage is converted to a digital value and processed in the Digital Signal Processing 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 memory 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 parameters 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 LowLevel 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:
Sensitivity =
VSignal
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 calculates 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 readonly 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:

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:
VSignal max = VOQ + VSUP
Reference Level Register
The LOW-LEVEL and HIGH-LEVEL registers contain the reference values of the comparator.
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 coordinates 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 necessary 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.

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 recommended. It contains the hardware for the generation of the serial telegram for programming 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 mechanical 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.

– Output Mode
Select the output mode: switch (positive polarity)
– TC
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.

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 corresponding 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 information 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.

5.3. Ambient Temperature
Due to the internal power dissipation, the temperature on the silicon chip (junction temperature TJ) is higher than the temperature outside the package (ambient temperature TA).
T J = T A + T
At static conditions and continuous operation, the following equation applies:
T = I SUP V SUP R thJ
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 temperature TAmax can be calculated as:
T Amax = T Jmax – T
5.4. EMC and ESD
Please contact TDK-Micronas for the detailed investigation reports with the EMC and
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 Acknowledge 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.

6.4. Number Formats
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. Negative numbers start with “1”. In order to calculate the absolute value of the number, calculate the complement of the remaining digits and add “1”.
Example: 0101001 represents +41 decimal
1010111 represents 41 decimal

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 is necessary 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.

HAL 1002
DATA SHEET
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 command 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
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 output signal.
Note
Electrostatic discharges (ESD) may disturb the programming pulses.
Please take precautions against ESD.
