1.1. Features
– High-precision linear Hall-effect sensor
– Spinning current offset compensation
– 20 bit digital signal processing
– Output resolution up to 16 bit
– Magnetic measurement range over temperature
adjustable from ±24 mT up to ±96 mT
– Sample period programmable from 0.5 ms to 33 ms
– Various sensor parameter are programmable: off-
set, sensitivity, temperature compensation for sensi-
tivity (2
nd
order) and offset (1
st
order), etc.
– Programming and operation of multiple sensors at
the same supply line
– Biphase-M interface (programming mode)
– Non-volatile memory with lock function
– SENT clock tick time programmable between 2 µs
and 17.75 µs
– Pulse low time programmable between 3 and
6.75 clock ticks
– Sample accurate transmission of magnetic field
information
– Transmission of temperature and device information
by serial data messages in the status nibble
– Open-drain output with slew rate control (load inde-
pendent)
– On-board diagnostics (overvoltage, output current,
overtemperature, signal path overflow)
– Power-on self-test covering all memories and full
signal path from Hall plates to SENT output
– ESD protection at DIO pin
– Reverse voltage and ESD protection at VSUP pin
– High immunity against mechanical stress, ESD, and
EMC
– AECQ-100 rev. G qualified
HAL 283x features a temperature-compensated Hall
plate with spinning-current offset compensation, an
A/D converter, digital signal processing, an EEPROM
memory with redundancy and lock function for the cali-
bration data, and protection devices at all pins. The
internal digital signal processing is of great benefit
because analog offsets, temperature shifts, and
mechanical stress do not degrade digital signals.
The easy programmability allows a 2-point calibration
by adjusting the output signal directly to the input sig-
nal (like mechanical angle, distance, or current). Indi-
vidual adjustment of each sensor during the cus-
tomer’s manufacturing process is possible. With this
calibration procedure, the tolerances of the sensor, the
magnet, and the mechanical positioning can be com-
pensated in the final assembly.
In addition, the temperature-compensation of the Hall
IC can be fit to all common magnetic materials by pro-
gramming first- and second-order temperature coeffi-
cients of the Hall sensor sensitivity. It is also possible
to compensate offset drifts over temperature gener-
ated by the customer application with a first-order tem-
perature coefficient of the sensor offset. This enables
operation over the full temperature range with high
accuracy.
For programming purposes, the sensor features a pro-
gramming interface with a Biphase-M protocol on the
DIO pin (output).
In the application mode, the sensor provides a continu-
ous SENT data stream.
