The built-in dynamic offset cancellation and temperature compensation of pre-amplifier stage achieves accuracy magnetic sensing. The wide supply voltage range is from 3.8V to 24V and the maximum output current is 50mA. This Hall-effect sensor IC integrated the Hall plate, pre-amplifier with dynamic offset cancellation, hysteresis comparator and protection circuit in single chip.
