TCAN1145-Q1: power supply sequence

Part Number: TCAN1145-Q1

Hello Experts,

Are there any limitation for power supply sequence for VSUP, VIO and VCC? I didn't get any information from the datasheet.

Best Regards,
Fujiwara

    Fujiwara-san,

    No, since there are UV thresholds and timers, any power up sequence will work as long as these timers are met. Specifically, the tUV timer for VIO and VCC once VSUP is present. If this timer elapses, the device will go into sleep mode automatically. 

    Please let me know if you have any other questions.

    Regards,
