BQ24278 CHG LED Odd Behavior

Hi,

Some odd behavior has been noticed on the BQ24278.  When the battery is fully charged, disconnected from external power supply, and then reconnected to power, the CHG LED remains on for up to 20 minutes even though the battery is fully charged and the charging current is at 0.0 A.  Is there a reason why this would occur and is there any work around?

Thanks,

Adrian
