The HAL 15xy family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an output stage. The sensors are designed for industrial and automotive applications and operate with supply voltages from 2.7 V (3-wire) or 3 V (2-wire) to 24 V in junction temperature range from-40 °C up to 170°C .
