DRV8860PWR from Texas Instruments, in a TSSOP-16. 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 | VM | power_in | Motor power supply plus pin; supply voltage range 8 to 38 V, bypass to GND with 0.1 μF ceramic and 10 μF electrolytic capacitors. |
| 2 | DIN | input | Serial data input from controller with internal pulldown resistance of 100 kΩ. |
| 3 | CLK | input | Serial clock input; rising edge clocks data into device for write operations, falling edge clocks data out for read operations; internal pulldown resistance of 100 kΩ. |
| 4 | LATCH | input | Serial latch signal for latching data into output register; internal pulldown resistance of 100 kΩ. |
| 5 | GND | power_in | Device ground; all pins must be connected to ground. |
| 6 | DOUT | output | Serial data output to controller; open-drain output with internal pullup resistance of 1.4 kΩ to internal 5.7 V. |
| 7 | nFAULT | tri_state | Fault output driven logic low when in fault condition (OCP, OTS, UVLO, OL); open-drain output requiring external pullup to V3P3, typical pullup resistor greater than 4.7 kΩ. |
| 8 | ENABLE | input | Logic high enables output drivers, logic low disables outputs and allows internal logic and control register read/write operations; internal pulldown resistance of 100 kΩ. |
| 9 | OUT8 | output | Low-side NFET output driver 8; connect external load between this pin and VM, internally limited output current. |
| 10 | OUT7 | output | Low-side NFET output driver 7; connect external load between this pin and VM, internally limited output current. |
| 11 | OUT6 | output | Low-side NFET output driver 6; connect external load between this pin and VM, internally limited output current. |
| 12 | OUT5 | output | Low-side NFET output driver 5; connect external load between this pin and VM, internally limited output current. |
| 13 | OUT4 | output | Low-side NFET output driver 4; connect external load between this pin and VM, internally limited output current. |
| 14 | OUT3 | output | Low-side NFET output driver 3; connect external load between this pin and VM, internally limited output current. |
| 15 | OUT2 | output | Low-side NFET output driver 2; connect external load between this pin and VM, internally limited output current. |
| 16 | OUT1 | output | Low-side NFET output driver 1; connect external load between this pin and VM, internally limited output current. |
