DRV8811: Power up sequence of Vcc and VM

Other Parts Discussed in Thread: DRV8811

Is DRV8811 necessary to keep power up sequence (timing) of Vcc and VM? 

Or, is sequence no required?

And, Is it the same as other DRV series?

Best regards,

Satoshi

    Hi Satoshi,

    Most other DRV don't have VCC line. It is better to have VCC and VM alive together. And it will be no big issue of which cames first a little. Note if only the VCC presented, the device internal logic may get half powered even without VM.

    Best regards,
