Low-cost Hall Switch Family HAL 2xy

The Hal 2xy Hall switch family is produced in CMOS
technology. The 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). Accordingly, the output transistor is switched on or off.
The active offset compensation leads to magnetic parameters,
which are robust against mechanical stress effects. in addition,
the magnetic characteristics are constant in the full supply voltage
and temperature range.
