The bq24715 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 component 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 bq24715 provides N-channel ACFET and RBFET drivers for the power path management. It also provides driver of the external P-channel battery FET. The loop compensation is fully integrated.

The bq24715 has programmable 11-bit charge voltage, 7-bit input/charge current and 6-bit minimal system voltage with very high regulation accuracies through the SMBus communication interface.

The v monitors adapter current or battery discharge current through the IOUT pin allowing the host to throttle down CPU speed when needed.

The bq24715 provides extensive safety features for over current, over voltage and MOSFET short circuit.
