TMR2301AHSO 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 | Power supply pin for the TMR2301A; the operating supply range is 1.8 V to 5.5 V, and the absolute maximum VDD is 6 V. |
| 2 | Gnd | power_in | Ground pin of the device, which the datasheet specifies as pin 2 (Gnd) on the SOT-23-3L package. |
| 3 | Out | output | Push-pull CMOS output pin; the absolute maximum output drive current (IOUTPUT) is 5 mA. |
