Hall Switch Family HAL 1xy

These Hall sensors are produced in CMOS technology
and 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.
