HAL2481LSO 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 with a working voltage of 2.5 V to 5.5 V (typical 3 V) and an absolute maximum VDD of 6.5 V. |
| 2 | Gnd | power_in | Ground pin for the device. |
| 3 | Out | output | Output pin; the pinout labels it push-pull, while the functional description says the output transistor is open-drain, and the absolute maximum output voltage is listed as 5 V in the ratings table. |
