Hi TI team,

In supplement mode, I understand that the BATFET OCP will work and latch-off the BATFET when the discharge current from battery will be higher than 9A.

I have some question as below:

1. How to exist this mode: 

A. Firstly we should unplug to enter shipmode.

B. Then we should plug VBUS again to exist shipmode.

Please confirm my understanding is right or not?

2. After trigger OCP during supplement mode, how to response if press /QON time longer than the tSHIPMODE?

 

Thanks very much!

BR

    Eleven,

    It is highly recommended to get familiar with the device operations by testing the device EVM

    1. Unplug and re-plug in the adaptor

    2. Should be the same. The key is a logic high to low transition on QON pin.

    Thanks,

    Ning.
