TCAN1044AV-Q1: HW: Power-on and off order for TCAN1044AVDRQ1

Nakayama Kentaro
Intellectual 935 points

Part Number: TCAN1044AV-Q1

Tool/software:

Hello experts,

Please let me confirm the order in which TCAN1044AVDRQ1 is powered on and off.

In our system,

Rising; VIO(3.3V) rises first and VCC(5.0V) rises later.

Falling: VCC(5.0V) falls first and VIO(3.3V) falls after.

We have determined that there is no problem in terms of absolute maximum ratings of the terminals.

I would like to know if there is any signal leakage or any other problem.

BR,

Kentaro
