Hallwee · Hall Switches · SOT-23-3L
HAL41FSO from Hallwee, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply voltage pin; the datasheet lists an absolute maximum VDD of 80 V, supply reverse-voltage protection, and an overvoltage capability of 80 V. |
| 2 | Gnd | power_in | Ground pin for the sensor circuit. |
| 3 | Out | output | Open-drain output pin that delivers a digital voltage signal switched by the Schmitt-trigger stage in response to the magnetic field; an external pull-up resistor is required (application circuit uses RL = 4.7 kΩ). |
