The US2881 is a bipolar Hall-effect switch designed in mixed signal CMOS technology.
The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver, all in a single package.
Thanks to its wide operating voltage range and extended choice of temperature range, it is suitable for use in automotive and consumer applications.
The device is delivered in a TSOT for surface mount process and in a Plastic Single In Line (TO-92 flat) for through-hole mount. Wide operating voltage range from 3.5 V to 24 V
