TMR2301ALSO 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 specifies an operating supply range of 1.8 V to 5.5 V and an absolute maximum VDD of 6 V. |
| 2 | GND | power_in | Ground pin of the device (pin 2 per the SOT-23 pin assignment). |
| 3 | Out | output | Push-pull CMOS output that goes low when the field exceeds BOP and high when it falls below BRP, with an absolute maximum output drive current of 5 mA. |
