HAL4901SO from Hallwee, in a SOT-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 voltage input; operating range 2.5 V to 6.5 V (typ 5.0 V), quiescent current 1.4-2.8 mA at VDD=3.3 V. |
| 2 | GND | power_in | Ground reference pin; connect to system ground. |
| 3 | OUT | output | Analog voltage output proportional to applied magnetic field; rail-to-rail, 0.0 V min to 5.0 V max at VDD=3.3 V, typical sensitivity 15 mV/Gs. |
