Hi Team,

Could you provide concept and schematic for wake up for MCU when USB plug in? Thanks.

  • Hi Cao cao,

    TPS2554 is a USB power switch on Vbus, can't be used to wake up MCU when USB plug in.

    What kind of plug in device you want to wake up your MCU, high speed, low speed, or full speed device?

    You may need monitor the voltage/signal on the D+ / D- pin, and judge accordingly.
