Hi team,

My customer has a question regarding the power up sequence of TPS1HTC30-Q1 and TPS1HTC100-Q1. Is it acceptable for them to power up VS pin after powering up EN pin, LATCH pin and DIAG_EN pin?

Best regards,

Yamamoto-san,

This should not be an issue, but I will double check with our design team tomorrow morning and get back to you.

Best Regards,
Tim

Yamamoto-san,

I confirmed with design that this will not be a problem. The device specifically has UVLO protection that makes sure there are not any problems with putting the digital pins high before VS.

Best Regards,
Tim
