GH143F Single-Pole Switch Hall Position Sensor
The GH143F series is a high-temperature unipolar Hall effect integrated sensor designed for consumer and industrial electronic products. It features a wide operating voltage range, high output current, fast switching speed without jitter, wide operating frequency, long lifespan, compact size, and easy installation. It can directly interface with logic circuits. The sensor comprises an internal voltage regulator, Hall voltage generator, differential amplifier, temperature compensation unit, Schmitt trigger, and an open-collector output stage. It operates with a single magnetic pole and is suitable for use with rectangular or cylindrical magnets. The GH143F operates from -40 to 150 with a supply voltage range of 3.8V to 30V and a load current capability of up to 50mA, packaged in a SIP3L (TO-92S) form factor.
