The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, small signal amplifier, Schmitt trigger and an open-drain output driver. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150℃, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. Thanks to its wide operat...
