HAL 5xy
Multipurpose Hall-Effect Sensor Family
The HAL 5xy family consists of different
Hall switches produced in CMOS technol-
ogy. All sensors include a temperature-
compensated Hall plate with active offset
compensation, a comparator, and an open-
drain output transistor. The comparator
compares the actual magnetic flux through
the Hall plate (Hall voltage) with the fixed
reference values (switching points). Accord-
ingly, the output transistor is switched on or
off.
The sensors of this family differ in the
switching behavior and the switching points.
The active offset compensation leads to
constant magnetic characteristics over sup-
ply voltage and temperature range. In addi-
tion, the magnetic parameters are robust
against mechanical stress effects.
The sensors are designed for industrial and
automotive applications and operate with
supply voltages from 3.8 V to 24 V in the
ambient temperature range from –40 °C up
to 150 °C.
All sensors are available in the SMD-pack-
age SOT89B-1 and in the leaded versions
TO92UA-1 and TO92UA-2.
