Description

The AH3761 is a high sensitivity CMOS Halls effect latch sensor for single-phase brushless DC (BLDC) fans and motor commutation applications. The AH3761 has an integrated band-gap voltage regulator, Hall-voltage transducer, amplifier, chopper stabilization, Schmitt trigger and open-drain output. With wide operating voltage and temperature range, AH3761 is a small versatile Hall-effect latch devices that turns on with south magnetic field of sufficient strength and turns off with north magnetic field of sufficient strength. It retains the output state when magnetic field is removed. The AH3761 is available in SC59 (SOT23) and SIP3 (TO-92) packages.
