# DRV8872DDARQ1

**Texas Instruments** · Brushed DC Motor Drivers · SO-8

DRV8872DDARQ1 from Texas Instruments, in a SO-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 | GND | power_in | Logic ground, connect to board ground. |
| 2 | IN2 | input | Logic input with internal pulldown controlling H-bridge output state. |
| 3 | IN1 | input | Logic input with internal pulldown controlling H-bridge output state. |
| 4 | nFAULT | tri_state | Open-drain fault output, pulled low by UVLO, TSD, or OCP fault conditions, requires external pullup resistor. |
| 5 | VM | power_in | 6.8V to 45V power supply input, requires 0.1µF bypass and bulk capacitance rated for the supply voltage. |
| 6 | OUT1 | output | H-bridge output for motor phase control, connect directly to motor or other inductive load. |
| 7 | ISEN | power_in | High-current ground return path for current regulation, connect low-value resistor to ground for regulated current limiting. |
| 8 | OUT2 | output | H-bridge output for motor phase control, connect directly to motor or other inductive load. |
