GR · Supervisor And Reset ICs · SOT-23
GR7030 from GR, in a SOT-23. 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 | OUT | output | Chip output pin; the output voltage is limited to GND-0.3 V to VDD+0.3 V, and the output sink current IOL is 0.5 mA minimum (1 mA typical) at VDD = 2 V with VOUT = 0.2 V. |
| 2 | GND | power_in | Chip ground pin, the reference for the supply and output voltage limits. |
| 3 | VDD | power_in | Chip input supply pin; the operating voltage range is 1.5 V to 12 V and the absolute maximum input voltage is 15 V. |
