GR61CN4402MR from GR, in a SOT-23-3. 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 | VOUT | output | Chip output terminal, available as either CMOS output or N-channel open-drain output; the absolute maximum output voltage is VSS-0.3 V to VIN+0.3 V, and the output sink current IOL is at least 0.5 mA at VDD=2 V with VOUT=0.2 V. |
| 2 | VSS | power_in | Chip ground terminal; the reference for the supply and output voltage limits (VOUT maximum is VSS-0.3 V). |
| 3 | VIN | power_in | Start/supply input terminal; operating voltage is 1.5 V to 12 V, and the absolute maximum input voltage is 15 V. |
