HAL245UA 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 | Positive supply pin with an operating range of 3.5 V to 24 V and an absolute maximum supply voltage of 28 V. |
| 2 | Gnd | power_in | Ground reference pin for the supply and the open-drain output. |
| 3 | Out | output | Open-drain output that goes low when the field reaches BOP and returns high below BRP; it requires an external pull-up resistor of 1K to 10K and the output current is limited to 10 mA maximum. |
