Two-Wire Hall-Effect Sensor Family
in CMOS technology
Release Note: Revision bars indicate significant
changes to the previous edition.
DATA SHEET
– the decrease of magnetic flux density caused by ris-
ing temperature in the sensor system is compen-
sated by a built-in negative temperature coefficient
of the magnetic characteristics
– ideal sensor for applications in extreme automotive
and industrial environments
– EMC corresponding to ISO 7637
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
external 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 volt-
age) with the fixed reference values (switching points).
Accordingly, the current source is switched on (high
current consumption) or off (low current consumption).
The active offset compensation leads to 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 automo-
tive 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 package SOT89B-1 and in the leaded versions
TO92UA-1 and TO92UA-2.

Unipolar Switching Sensors:
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the pack-
age and turns to low consumption if the magnetic field
is removed. The sensor does not respond to the mag-
netic north pole on the branded side.
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
magnetic fields up to 10 kHz
– switching offset compensation at typically 145 kHz
– overvoltage and reverse-voltage protection
– magnetic characteristics are robust against
mechanical stress effects
– constant magnetic switching points over a wide sup-
ply voltage range

1.3. Marking Code
All Hall sensors have a marking on the package sur-
face (branded side). This marking includes the name
of the sensor and the temperature range.
Unipolar Inverted Switching Sensors:
The sensor turns to low current consumption with the
magnetic south pole on the branded side of the pack-
age and turns to high consumption if the magnetic field
is removed. The sensor does not respond to the mag-
netic north pole on the branded side.

Latching Sensor:
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the pack-
age and turns to low consumption with the magnetic
north pole on the branded side. The current consump-
tion does not change if the magnetic field is removed.
For changing the current consumption, the opposite
magnetic field polarity must be applied.

Note:
Due to the high power dissipation at high current
consumption, there is a difference between the

) and junction tempera-
ture. Please refer to Section 5.4. on page 34 for
