TPS4812-Q1: Bi-direction load current wakeup

Hi team,

Can the G pin of TPS48120-Q1 be used to drive back to back MOSFET and support bi-direction load current wakeup? Thanks!

Best Regards

    Hi Grey, 

    You can setup back to back FETs on the LPM path similar to the picture below. 

    Are you asking whether the device will support automatic load wakeup with reverse current? With the b2b FET configuration will block reverse current if the FETs are not already on. 

    Thanks,

    Sarah
