Part Number: DRV8885

Hello,

Our customer use the DRV8885.

The DRV8885 does not have RESET pin.

So the customer reset the device using nSLEEP.

I attach the file shows the sequence of reset.

Is there a spec of the timing from nSLEEP High to ENABLE High?

Hi Aoyama-san,

There is no spec from nSLEEP High to ENABLE High.

ENABLE can be set to High at any time. It is recommended to set ENABLE Low when in sleep mode. This will prevent current flow through the pulldown resistor.
