Introduction
The HAL62x family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate with active offset compensation, a filter, 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 sensors of this family differ in their magnetic characteristics.

FEATUREs:
– switching offset compensation at typically 360 kHz
– signal processing with chopper stabilized filter
– operates from 4.2 V to 24 V supply voltage
– operates with static magnetic fields and dynamic magnetic fields up to 15 kHz
– overvoltage protection at all pins
– reverse-voltage protection at VDD-pin
– magnetic characteristics are robust against mechanical stress effects
– short-circuit protected open-drain output by thermal shut down
– constant switching points over a wide supply voltage range
– ideal sensor for applications in extreme automotive and industrial environments
– EMC and ESD optimized design
