BQ25713 charges battery from a wide range of input sources including usb adapter, high voltage usb pd sources and traditional adapters. during power up, the charger sets converter to buck, boost or buck-boost configuration based on input source and battery conditions. the charger automatically transits among buck, boost and buck-boost configuration without host control. in the absence of an input source, BQ25713 supports usb on-the-go (otg) function from 1- to 4-cell battery to generate adjustable 3 v to 20.8 v on vbus with 8 mv resolution. the otg output voltage transition slew rate can be configurable, which is complied with the usb pd 3.0 pps specifications. BQ25713 monitors adapter current, battery current and system power. the flexibly programmed prochot output goes directly to cpu for throttle back when needed. advance information
