AH3711Q

The AH3711Q is an automotive Hall-effect latch from Diodes, a bipolar switch that turns on with a south pole and off with a north pole at tight +/-10 G typical operate and release points, for BLDC commutation, speed sensing and position detection in automotive and industrial motors. The wide 3 V to 27 V supply range rides through automotive transients, with 40 V load-dump tolerance, and the open-drain output includes overcurrent limiting. Chopper stabilisation keeps the magnetic thresholds stable over temperature and supply, minimises drift and resists physical stress, while a reverse blocking diode and supply Zener clamp add robustness; ESD withstand is 8 kV HBM and 1 kV CDM. The device is AEC-Q100 qualified, PPAP capable and rated from -40 C to +150 C. The base code AH3711Q is offered in SOT23 (Type S), SC59 and SIP-3 packages (ordering suffixes SA-7, W-7 and P-B), so confirm the package suffix in your RFQ, as footprint and pinout differ between them. Parameters verified against Diodes Incorporated documentation.
