# GR6212

**GR** · Brushed DC Motor Drivers · SOP-8

GR6212 from GR, in a SOP-8. 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 | VCC | power_in | Positive supply pin; operating voltage is 3.0 V to 15 V, and the absolute maximum supply voltage is 16.0 V. |
| 2 | OUTA | output | Motor driver output A; maximum output current is 100 mA at VDD=15 V (Ta=25 °C). |
| 3 | GND | power_in | Power ground pin for the supply and logic. |
| 4 | OUTB | output | Motor driver output B; maximum output current is 100 mA at VDD=15 V (Ta=25 °C). |
| 5 | INB | input | Logic input B, TTL/CMOS compatible; at VDD=15 V the high level is at least 2.5 V and the low level is at most 1.5 V. |
| 6 | NC | unconnected | No connection (marked as an empty pin in the datasheet). |
| 7 | GND | power_in | Second power ground pin, listed separately from pin 3 in the datasheet table. |
| 8 | INA | input | Logic input A, TTL/CMOS compatible; at VDD=15 V the high level is at least 2.5 V and the low level is at most 1.5 V. |
