Two-Wire Hall Effect Sensor Family
in CMOS technology
1. Introduction
This sensor family consists of different two-wire Hall
switches produced in CMOS technology. All sensors
change the current consumption depending on the ex-
ternal magnetic field and require only two wires between
sensor and evaluation circuit. The sensors of this family
differ in the magnetic switching behavior and switching
points.
The sensors include a temperature-compensated Hall
plate with active offset compensation, a comparator, and
a current source. The comparator compares the actual
magnetic flux through the Hall plate (Hall voltage) with
the fixed reference values (switching points). According-
ly, the current source is switched on (high current
consumption) or off (low current consumption).
The active offset compensation leads o constant mag-
netic characteristics in the full supply voltage and tem-
perature range. In addition, the magnetic parameters
are robust against mechanical stress effects.
The sensors are designed for industrial and automotive
applications and operate with supply voltages from 3.75
V to 24 V in the junction temperature range from –40
°
C
up to 140
°
C. All sensors are available in the SMD-pack-
age SOT-89B and in the leaded version TO-92UA.
1.1. Features:
– current output for two-wire applications
– low current consumption: 5 mA ... 6.9 mA
– high current consumption: 12 mA ... 17 mA
– junction temperature range from –40
°
C up to 140
°
C.
– operates from 3.75 V to 24 V supply voltage
– operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
– switching offset compensation at typically 145 kHz
– overvoltage and reverse-voltage protection
– magnetic characteristics are robust against mechani-
cal stress effects
– constant magnetic switching points over a wide supply
voltage range
– the decrease of magnetic flux density caused by rising
temperature in the sensor system is compensated by
a built-in negative temperature coefficient of the mag-
netic characteristics
– ideal sensor for applications in extreme automotive
and industrial environments
– EMC corresponding to DIN 40839

Unipolar Switching Sensors:
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the package
and turns to low consumption if the magnetic field is
removed. The sensor does not respond to the magnetic
north pole on the branded side.
