WH2508F-3

WILLSEMI Will Semicon · Hall Sensor · TSOT-23-3L

WH2508F-3 from WILLSEMI Will Semicon, in a TSOT-23-3L. 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 1.6 V to 5.5 V; absolute maximum 6 V. Bypass with a small ceramic capacitor (C_IN) to GND close to the pin.
2 OUTPUT output Push-pull Hall-switch output. Drives low (VOL ≈ 0.085 V @ 5 mA) when the perpendicular magnetic flux density exceeds BOP and drives high (VOH ≈ VDD-0.085 V @ 5 mA) when it falls below BRP. Maximum output current 5 mA. Operates in omnipolar mode (asserts on either N or S pole).
3 GND power_in Device ground return.
