bq24715J Description
The bq24715J is a NVDC-1 synchronous battery charge controller with low quiescent current, high light load efficiency for 2S or 3S Li-ion battery charging applications, offering low ponent count. The power path management allows the system to be regulated at battery voltage but does not drop below the programmable system minimum voltage. The device provides N-channel ACFET and RBFET drivers for the power path...
