GR7889

GR · Brushed DC Motor Drivers · SOP-8

GR7889 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 INA input Control signal input for channel A; the datasheet specifies VINL 0 to 0.7 V and VINH 2 to 6 V for INA and INB.
2 INB input Control signal input for channel B; the datasheet specifies VINL 0 to 0.7 V and VINH 2 to 6 V for INA and INB.
3 GND power_in Power ground for the device.
4 VCC power_in Positive supply pin with an operating range of 2 to 20 V and an absolute maximum of -0.3 to +23 V.
5 OB output Channel B driver output, bonded in parallel with pin 6; the datasheet requires adequate copper pour around OA and OB for heat dissipation when driving large loads.
6 OB output Channel B driver output, bonded in parallel with pin 5; the datasheet requires adequate copper pour around OA and OB for heat dissipation when driving large loads.
7 OA output Channel A driver output, bonded in parallel with pin 8; the datasheet requires adequate copper pour around OA and OB for heat dissipation when driving large loads.
8 OA output Channel A driver output, bonded in parallel with pin 7; the datasheet requires adequate copper pour around OA and OB for heat dissipation when driving large loads.
