TPS65987D: waking up MCU when USB cable is plugged in

Part Number: TPS65987D

Team, my customer has a question:

We need a signal from the TPS65987D that will wake up a microcontroller when a USB cable is plugged in.  It's not clear to me which signal can be used for this?

Secondly, if this signal is required to be configured at initialization, is this something we can set in our configuration NOR flash?

Thanks

Viktorija

    Hi Viktorija,

    There are several different options for this behavior with TPS65987D. You could configure a GPIO to be enabled on the "Plug Event" GPIO event. Or you could set up an I2C interrupt to the EC for "Plug Insert or Removal".

    Thank you,
