AH3712-SA-7

Diodes Incorporated · Linear Hall Sensors · SOT-23-3

AH3712-SA-7 from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Power supply input. Operating range 3.0V to 27V (absolute max 40V transient, load-dump up to 40V). Reverse supply rated to -18V. Recommended 10nF-100nF decoupling capacitor (CIN) to GND. Typical supply current IDD ≈ 2.8mA (max 4.8mA over temp).
2 GND power_in Ground reference for the device. Return for VDD, output current, and internal Hall-sensor bias circuits.
3 OUTPUT output Open-drain latch output (AH3712 variant; AH3712A includes internal ~14kΩ pull-up, AH3712B is inverted). Requires external pull-up resistor RL to VDD. VOUT_ON ≈ 0.25V typ (max 0.42V) at 20mA sink; output leakage <0.1µA typ at 27V off. Sinks up to 60mA absolute max with internal current limit IOCL of 30-60mA. Rated to 40V off-state; 36V zener clamp.
