GR · Supervisor And Reset ICs · SOT-23-3
GR61CN3502MR 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 pin, which is an N-channel open-drain output or CMOS output depending on the variant; the datasheet gives the absolute maximum output voltage as VSS-0.3 V to VIN+0.3 V. |
| 2 | VSS | power_in | Chip ground pin. |
| 3 | VIN | power_in | Startup/supply input pin; the operating voltage range is 1.5 V to 12 V, and the absolute maximum input voltage is 15 V. |
