TCAN1145-Q1: question about TCAN1145-Q1

Part Number: TCAN1145-Q1

Tool/software:

Hello：

The customer is using TI's TCAN1145 and would like to confirm the significance of the tpwrup parameter. Currently, TCAN1043 does not have this maximum value, but TCAN1145 does have a maximum value requirement. Is it all for supplying power to the MCU? What does it matter to be slower? Thank you！！！

    Jimmy,

    This isn't a requirement, it is just saying the maximum amount of time for INH to go high after VSUP passes the under voltage threshold is 4ms. Designers can use this to properly time their system power up if INH is being used as an enable for the power supply in the system.

    Regards,
