The device integrates a voltage regulator, reverse battery protection diode, Hall sensor with dynamic offset cancellation system, temperature compensation circuitry, small signal amplifier, Schmitt trigger and an open-collector output to sink up to 25 mA. 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. If a magnetic flux density larger than threshold Bop, Output is turned on (low). The output state is held u...
