BQ25756E: BQ25756E Reverse output mode problem

Part Number: BQ25756E

Hi 

When BQ25756E works in reverse output mode, it automatically turns off the output for about 40 seconds, and then turns it back on - EN_REV, and can output for another 40 seconds. And so on. The output current, output voltage can be set, and the temperature protection has been turned off. Charging function is normal. What else do I need to check?

Waiting for your reply.

Thanks

Star

    Can you please clarify, during the entire duration of this test, there was not VAC (input voltage) connected ? Are you saying that in your case, when the reverse mode is working, suddenly it stops working for 40s and then starts working again for 40s and so on and so forth ? Please also let me know your reverse voltage and current settings.
