DRV8839DSSR from Texas Instruments, in a WSON-12-EP(2x3). 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 | VM | power_in | Motor supply voltage input (0V to 11V); bypass to ground with 0.1-μF, 16-V ceramic capacitor. |
| 2 | VM | power_in | Motor supply voltage input (0V to 11V); bypass to ground with 0.1-μF, 16-V ceramic capacitor. |
| 3 | OUT1 | tri_state | H-bridge output 1 for motor winding; tri-state output controlled by EN1 (enable) and IN1 (direction/state). |
| 4 | OUT2 | tri_state | H-bridge output 2; tri-state output controlled by EN2 (enable) and IN2 (direction/state). |
| 5 | GND | power_in | Device ground connection. |
| 6 | GND | power_in | Device ground connection. |
| 7 | EN2 | input | Logic input to enable H-bridge 2 output; logic high enables OUT2, internal pulldown resistor. |
| 8 | IN2 | input | Logic input controlling H-bridge 2 state; internal pulldown resistor. |
| 9 | EN1 | input | Logic input to enable H-bridge 1 output; logic high enables OUT1, internal pulldown resistor. |
| 10 | IN1 | input | Logic input controlling H-bridge 1 state; internal pulldown resistor. |
| 11 | nSLEEP | input | Sleep mode input; logic low enters low-power sleep mode, logic high for normal operation, internal pulldown resistor. |
| 12 | VCC | power_in | Logic supply voltage input (1.8V to 7V); bypass to ground with 0.1-μF, 6.3-V ceramic capacitor. |
| 13 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
