DRV8873-Q1: EN/IN1, PH/IN2 termination during SPI_IN=1b

Akihiro Hirata

Part Number: DRV8873-Q1

Hello team,

If we use DRV8873-Q1 and control the motor through SPI register (SPI_IN = 1b), then we can leave the EN/IN1, PH/IN2 pins open because it has internal pull down, correct?

Hi Hirata san.

Yes, it is correct.

And recommend to set Disable pin =H first during wake up sequence. After SPI configuration is done, make Disable pin=L low to enable output.

Please refer datasheet 7.4
