Hallwee · Hall Switches · TO-92S
HAL41FUA from Hallwee, in a TO-92S. 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 supply voltage of 80 V and states reverse-voltage protection on the supply pin. |
| 2 | Gnd | power_in | Ground pin. |
| 3 | Out | output | Open-drain output pin; the datasheet lists an absolute maximum output voltage of 40 V and output current of 40 mA. |
