The AH3774 is a high-voltage, high-sensitivity Hall-effect latch IC designed for brushless DC motor commutation, flow meters, and position sensing in industrial and consumer applications. It operates from a 3.0V to 28V supply, features a single open-drain output with overcurrent limiting, and employs a chopper-stabilized design for temperature stability and low switch point drift. The device has a typical magnetic operate and release point of ±40G and is rated for operation from -40°C to +125°C. It is available in the SOT-23 package, which requires a south pole applied to the part-marking side to activate. The part includes a reverse-blocking diode and Zener clamp on the supply, and an ESD HBM rating of 6kV. It is RoHS compliant and lead-free. The AH3774-SA-7 variant is packaged in 7" tape & reel with a quantity of 3,000 per reel.
