BQ24610RGET -Impact of connecting battery with wrong polarity


We have used BQ24610RGET battery charger IC in our module,we noticed that the LED connected to PG pin of the IC is  Blinking on providing Adapter I/P supply, even though Adapter supply seems to be good and we confirmed the same using a second board, where we found it functioning as expected.

This was not observed initially,  we are suspecting battery was connected with wrong polarity during testing ,which is causing this faulty behavior.

We too noticed no battery charge voltage is generated by IC at battery connection point.

Whether connecting battery with wrong polarity will  cause failure of IC or something else is causing the issue.
