DRV8434S: Sequencing Requirements

Austin Allen

Part Number: DRV8434S

Tool/software:

Are there any power sequencing requirements for VM, VREF, and VSDO? Is it okay if VSDO and VREF are applied with VM disabled. I want to make sure there aren't any issues with leakage if the DRV8434S is partially powered.

Thank you,

Austin Allen

Hi Austin,

No power sequencing requirements for VM, VREF and VSDO for the DRV8434S.

Yes this will be okay. While VM is not available DVDD will be absent. There won't be any SPI communication possible.
