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. |
