DRV8804DWR from Texas Instruments, in a SOIC-20-300mil. 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 | Device supply pin connected to the motor supply, specified for 8.2 V to 60 V. |
| 2 | VCLAMP | passive | Output clamp voltage pin connected to VM or to a Zener/TVS to VM to set the clamp voltage; the datasheet states it is not a power input and is limited to 0 V to 60 V. |
| 3 | OUT1 | output | Low-side driver output 1 connected to load 1, with an absolute maximum output voltage of 65 V. |
| 4 | OUT2 | output | Low-side driver output 2 connected to load 2, with an absolute maximum output voltage of 65 V. |
| 5 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 6 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 7 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 8 | OUT3 | output | Low-side driver output 3 connected to load 3, with an absolute maximum output voltage of 65 V. |
| 9 | OUT4 | output | Low-side driver output 4 connected to load 4, with an absolute maximum output voltage of 65 V. |
| 10 | nENBL | input | Active-low output enable with internal pull-down; outputs are enabled only when this pin is held low. |
| 11 | RESET | input | Active-high reset input with internal pull-down that resets internal logic including OCP faults and clears the serial interface registers. |
| 12 | NC | unconnected | Not connected; the datasheet specifies no function for this pin. |
| 13 | LATCH | input | Rising-edge latch input with internal pull-down that transfers the shift register data to the outputs; minimum pulse width 200 ns. |
| 14 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 15 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 16 | GND | power_in | Device ground; all ground pins must be connected to ground. |
| 17 | SCLK | input | Serial clock input with internal pull-down; each rising edge shifts in one data bit, with minimum clock period 62 ns. |
| 18 | SDATIN | input | Serial data input with internal pull-down, sampled on the SCLK rising edge with a minimum setup time of 5 ns. |
| 19 | SDATOUT | output | Push-pull serial data output for daisy-chaining that sources about 1 mA and sinks about 5 mA, and can drive another DRV8804 SDATIN up to 1 MHz without an external pull-up. |
| 20 | nFAULT | output | Open-drain fault output driven low during overtemperature or overcurrent, with VOL maximum 0.5 V at 5 mA and IOH maximum 1 µA at 3.3 V. |
