Other Parts Discussed in Thread: BQ24086

Hi,

Is STAT1/2 operation on recharge mode same as it on normal charge mode?

customer will connect red led to STAT1 and green to STAT2.

After full charge, green will turn on.

When BQ24086 goes to recharge by load, will red turn on? same as normal charge mode.

Thanks.

    Please refer to the datasheet page 20. When voltage on BAT pin falls to recharge threshold after termination, the bq24086 begins a battery absent detection test. This test involves checking if the battery voltage is below the pre-charge threshold and follows by checking if the battery voltage is above recharge threshold. Failure of either test starts a new charge cycle. The STAT1 and STAT2 will indicate charging. In this case, the RED LED turns on and GREEN LED turns off.
