DRV8847RTER from Texas Instruments, in a WQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ISEN12 | output | Full-bridge 12 current sensing output. Connect this pin to current-sensing resistor for full-bridge 12, or to GND if current regulation is not needed. |
| 2 | OUT2 | output | Half-bridge output 2 for motor phase control. |
| 3 | OUT4 | output | Half-bridge output 4 for motor phase control. |
| 4 | ISEN34 | output | Full-bridge 34 current sensing output. Connect this pin to current-sensing resistor for full-bridge 34, or to GND if current regulation is not needed. |
| 5 | OUT3 | output | Half-bridge output 3 for motor phase control. |
| 6 | nFAULT | tri_state | Fault indication pin pulled to logic low under fault, overtemp, or UVLO conditions; open-drain output requiring external pull-up resistor. |
| 7 | IN3 | input | Half-bridge input 3 for PWM gate drive control. |
| 8 | IN4 | input | Half-bridge input 4 for PWM gate drive control. |
| 9 | TRQ | input | Torque current scalar input; pull low for 100% torque or high for 50% torque scaling of output current. |
| 10 | VM | power_in | Motor power supply input; bypass to ground using 0.1µF ceramic and 10µF minimum capacitors rated at VM voltage. |
| 11 | GND | power_in | Device ground reference. Ground the GND pin and exposed thermal pad for proper thermal and electrical performance. |
| 12 | MODE | input | Three-state pin for bridge configuration selection: grounded for 4-pin mode, high for 2-pin mode, high for parallel mode, or floating for independent bridge mode. |
| 13 | IN2 | input | Half-bridge input 2 for PWM gate drive control. |
| 14 | IN1 | input | Half-bridge input 1 for PWM gate drive control. |
| 15 | nSLEEP | input | Sleep mode control input; set high to enable device operation, set low to enter low-power sleep mode with 1.7µA quiescent current. |
| 16 | OUT1 | output | Half-bridge output 1 for motor phase control. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
