5 Description (Continued)
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, the bq25703A supports On-the-Go (OTG) function from 1- to 4-cell battery to
generate 4.48 V to 20.8 V on VBUS. During OTG mode, the charger regulates output voltage and output current.
The bq25703A monitors adapter current, battery current and system power. The flexibly programmed PROCHOT
output goes directly to CPU for throttle back when needed.
