Hall-effect latch sensor - Low voltage and high sensitivity - US3881
Product description
The US3881 is a Hall-effect latch 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.
The low operating voltage and extended choice of temperature range make it suitable for use in automotive, industrial and consumer low voltage applications.
The devices are delivered in a TSOT for surface mount process and in a plastic single in line (TO-92 flat) for through-hole mount. Both 3-lead packages are RoHS compliant.
