Other Parts Discussed in Thread: BQ24745

HI, 

I have a question about BQ24745. Per spec sheet, it can charge Li-Ion, Li-Polymer, NiCD, NiMH and LEAD batteries.   However, I can't find instructions and settings of how to terminate a charge of NiMH and NiCD batteries.  Can someone help me on this topic?

Thanks,

Eric

    bq24745 is a host control charger. So, all charger current and voltage are set by a external EC or host controller.

    For NiMH or NICD battery termination, the host controller needs to send a command to bq24745 to stop charging. bq24745 can't be terminated by itself.
