Texas Instruments · Stepper Motor Driver · HTSSOP-16-EP
DRV8806PWPR from Texas Instruments, in a HTSSOP-16-EP. 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 power supply, connect to the motor supply; the datasheet specifies 8.2 V to 40 V. |
| 2 | VCLAMP | passive | Output clamp voltage, connected to the VM supply or to a zener/TVS diode to VM to clamp inductive turn-off transients; recommended range 0 to 40 V and it is not a power supply input. |
| 3 | OUT1 | output | Low-side driver output 1 connected to load 1; outputs must not exceed the 43 V absolute maximum output voltage. |
| 4 | OUT2 | output | Low-side driver output 2 connected to load 2; outputs must not exceed the 43 V absolute maximum output voltage. |
| 5 | GND | power_in | Device ground; all GND pins must be connected to ground. |
| 6 | OUT3 | output | Low-side driver output 3 connected to load 3; outputs must not exceed the 43 V absolute maximum output voltage. |
| 7 | OUT4 | output | Low-side driver output 4 connected to load 4; outputs must not exceed the 43 V absolute maximum output voltage. |
| 8 | nENBL | input | Active-low enable input (internal pulldown); outputs are enabled when driven low and disabled when driven high, with digital input limits of -0.5 V to 7 V. |
| 9 | RESET | input | Active-high reset input (internal pulldown) that initializes internal logic, clears the overcurrent fault and serial interface registers; digital input limits of -0.5 V to 7 V. |
| 10 | NC | unconnected | No connection shown in the pin configuration diagram; not listed in the Pin Functions table. |
| 11 | LATCH | input | Latch input (internal pulldown); a rising edge latches the shift register to the outputs and a falling edge latches fault data, with a minimum pulse width of 200 ns. |
| 12 | GND | power_in | Device ground; all GND pins must be connected to ground. |
| 13 | SCLK | input | Serial clock input (internal pulldown); data is shifted in on each rising edge with a minimum clock cycle time of 62 ns. |
| 14 | SDATIN | input | Serial data input (internal pulldown) sampled on the SCLK rising edge with 5 ns minimum setup time to SCLK. |
| 15 | SDATOUT | output | Serial data output with push-pull structure and internal pullup, able to drive another DRV8806 SDATIN up to 1 MHz without external pullup; sources about 1 mA and sinks about 5 mA. |
| 16 | nFAULT | output | Open-drain fault output driven low on overtemperature, overcurrent or open load, with output low voltage of 0.5 V max at 5 mA. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
