Programmable Linear Hall-Effect Sensors in TO92 Package
1. Introduction
HAL 188x is a preprogrammed Hall-effect sensor family with a ratiometric, linear analog
output proportional to the magnetic flux density applied to the sensor surface. The sen-
sor can be used for magnetic-field measurements such as current measurements and
detection of mechanical movement, like for small-angle or distance measurements. The
sensor is robust and can be used in harsh electrical and mechanical environments.
The spinning-current offset compensation leads to stable magnetic characteristics over
supply voltage and temperature. Furthermore, the first and seconds order temperature
coefficients of the sensor sensitivity can be used to compensate the temperature drift of
all common magnetic materials. This enables operation over the full temperature range
with high accuracy.
The different family members vary by sensitivity (25 mV/mT, 31.25 mV/mT, and
50 mV/mT). The output voltage response for zero magnetic field (apart from offset) is
50% of supply voltage for all product family members.

The sensors are designed for industrial and automotive applications, are AEC-Q100
qualified, and operate in the junction temperature range from –40 °C up to 170 °C.
HAL 188x is available in the very small leaded package TO92UA-1 and TO92UA-2.
1.1. Major Applications
Thanks to the sensors’ robust and cost-effective design, HAL 188x is the optimal sys-
tem solution for applications such as:
– Small-angle or linear position measurements
– Gear position detection in transmission application
– Current sensing for battery management
– Rotary selector

3. Functional Description
3.1. General Function
HAL 188x is a monolithic integrated circuit (IC) which provides an output voltage pro-
portional to the magnetic flux through the Hall plate and proportional to the supply volt-
age (ratiometric behavior).
The external magnetic field component perpendicular to the branded side of the package
generates a Hall voltage. The Hall IC is sensitive to magnetic north and south polarity.
This Hall voltage is converted to a digital value, processed by the Digital Signal Processing
unit (DSP), converted back to an analog voltage by a D/A converter and buffered by a
push-pull output stage. The function and the parameters for the DSP are explained in
Section 3.3. on page 8. Internal temperature compensation circuitry and the spinning-cur-
rent offset compensation enable operation over the full temperature range with minimal
degradation in accuracy and offset. The circuitry also rejects offset shifts due to mechani-
cal stress from the package. In addition, the sensor IC is protected against reverse polarity
at supply pin.

3.2. Output/Magnetic Field Polarity
Applying a south-pole magnetic field perpendicular to the branded side of the package
will increase the output voltage (for Sensitivity <0) from the quiescent (offset) voltage
towards the supply voltage. A north-pole magnetic field will decrease the output voltage.
3.3. On-board Diagnostic Features
HAL 188x features the following five diagnostic functions controlled by the DSP:
– Magnetic signal amplitude out of range (overflow or underflow in signal path)
– Over-/underflow in adder or multiplier
– Over-/underflow in A/D converter
These faults are visible at the output as long as present. The occurrence of these
faults forces the output to the error band (see VDIAG_L or VDIAG_H in Section 4.9. on
page 18).
– Undervoltage detection with internal reset
The occurrence of an undervoltage is indicated immediately by switching the output to
ground.
– Overtemperature: Thermal supervision of the output stage
(overcurrent, short circuit, etc.)
The sensor switches the output to tristate if an overtemperature is detected by the
thermal supervision.

4.5. Absolute Maximum Ratings
Stresses beyond those listed in the “Absolute Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only. Functional operation of the device at
these conditions is not implied. Exposure to absolute maximum rating conditions for
extended periods will affect device reliability.
This device contains circuitry to protect the inputs and outputs against damage due to
high static voltages or electric fields; however, it is advised that normal precautions
must be taken to avoid application of any voltage higher than absolute maximum-rated
voltages to this circuit.
All voltages listed are referenced to ground (GND).

5. Application Notes
5.1. Ambient Temperature
Due to the internal power dissipation, the temperature on the silicon chip (junction temper-
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 * RthjX
The X represents junction to air or to case.
In order to estimate the temperature difference T between the junction and the respec-
tive reference (e.g. air, case, or solder point) use the max. parameters for ISUP, RthX,
and the max. value for VSUP from the application.
The following example shows the result for junction to air conditions. VSUP = 5.5 V,
Rthja = 250 K/W and ISUP = 10 mA the temperature difference T = 13.75 K.
The junction temperature TJ is specified. The maximum ambient temperature TAmax can
be estimated as:
TAmax = TJmax T
Note
The calculated self-heating of the devices is only valid for the Rth test
boards. Depending on the application setup the final results in an applica-
tion environment might deviate from these values.
5.2. EMC
HAL 1880 is designed for a stabilized 5 V supply. Interferences and disturbances
conducted along the 12 V onboard system (product standard ISO 7637 part 1) are not
relevant for these applications.
For applications with disturbances by capacitive or inductive coupling on the supply line
or radiated disturbances, the application circuit shown in Fig. 5–1 on page 22 is recom-
mended. Applications with this arrangement should pass the EMC tests according to
the product standards ISO 7637 part 3 (electrical transient transmission by capacitive or
inductive coupling).

5.3. Application Circuit
For EMC protection, it is recommended to connect a 47 nF capacitor between ground
and output voltage pin as well as a 100 nF capacitor between supply and ground as
shown in Fig. 5–1.
