# DRV8847PWR

**Texas Instruments** · Stepper Motor Driver · TSSOP-16

DRV8847PWR from Texas Instruments, in a TSSOP-16. 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 | nSLEEP | input | Sleep mode input: set logic high to enable the device and logic low to enter low-power sleep mode. |
| 2 | OUT1 | output | Half-bridge output 1. |
| 3 | ISEN12 | output | Full-bridge-12 sense pin: connect to the current sense resistor for full-bridge-12, or to GND if current regulation is not required. |
| 4 | OUT2 | output | Half-bridge output 2. |
| 5 | OUT4 | output | Half-bridge output 4. |
| 6 | ISEN34 | output | Full-bridge-34 sense pin: connect to the current sense resistor for full-bridge-34, or to GND if current regulation is not required. |
| 7 | OUT3 | output | Half-bridge output 3. |
| 8 | nFAULT | output | Open-drain fault indication pin, pulled logic low on a fault condition; requires an external pullup resistor. |
| 9 | IN3 | input | Half-bridge input 3. |
| 10 | IN4 | input | Half-bridge input 4. |
| 11 | TRQ | input | Torque current scalar input that scales the output current. |
| 12 | VM | power_in | Motor power supply input; bypass to ground with a VM-rated 0.1-µF (ceramic) and 10-µF (minimum) capacitor. |
| 13 | GND | power_in | Device ground; connect the GND pin to ground. |
| 14 | MODE | input | Tri-state pin for selection of driver operating mode. |
| 15 | IN2 | input | Half-bridge input 2. |
| 16 | IN1 | input | Half-bridge input 1. |
