HAL 1000
Programmable Hall Switch
Release Note: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The HAL1000 is a programmable Hall 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 sensi-
tive to the south pole, with normal or with an electri-
cally inverted output signal. Several examples are
shown in Fig. 2–4 through Fig. 2–7.
The HAL1000 is based on the HAL 8xx family and fea-
tures a temperature-compensated Hall plate with
choppered offset compensation, an A/D converter, dig-
ital signal processing, a push-pull output stage, an
EEPROM memory with redundancy and lock function
for the calibration data, a serial interface for program-
ming 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 HAL1000 is programmable by modulating the
supply voltage. No additional programming pin is
needed. Programming is simplified through the use of
a 2-point calibration. Calibration is accomplished by
adjusting the sensor output directly to the input signal.
Individual 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 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
IC can be tailored to all common magnetic materials by
programming first and second order temperature coef-
ficients of the Hall sensor 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
Micronas.
The sensor is designed and produced in sub-micron
CMOS technology for 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 HAL1000 is available in the leaded packages
TO92UT-1 and TO92UT-2.
1.1. Major Applications
Due to the sensor’s versatile programming character-
istics, the HAL1000 is the optimal system solution for
applications which require very precise contactless
switching:
– end point detection
– level switch (e.g. liquid level)
– electronic fuse (current measurement)
WARNING:
DO NOT USE THESE SENSORS IN LIFE-
SUPPORTING SYSTEMS, AVIATION, AND
AEROSPACE APPLICATIONS.
1.2. Features
– high-precision Hall switch with programmable
switching points and switching behavior
– switching points programmable from 150 mT up to
150 mT in steps of 0.5% of the magnetic field range
– multiple programmable magnetic characteristics in a
non-volatile memory (EEPROM) with redundancy
and lock function
