This device is a synchronous NVDC buck-boost battery charge controller, offering a lowcomponent count, high efficiency solution for space constrained, 1s-4s battery chargingapplications.

The NVDC configuration allows the system to be regulated at battery voltage, but not dropbelow system minimum voltage. The system keeps operating even when the battery is completelydischarged or removed. When load power exceeds input source rating, the battery goes intosupplement mode and prevents the system from crashing.

BQ25713/BQ25713B charges battery from a wide range ofinput 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 configurationbased on input source and battery conditions. The charger automatically transits among buck, boostand buck-boost configuration without host control.

In the absence of an input source, BQ25713/BQ25713B supports USB On-the-Go (OTG) functionfrom 1- to 4-cell battery to generate adjustable 3 V to 20.8 V on VBUS with 8 mV resolution. TheOTG output voltage transition slew rate can be configurable, which is complied with the USB PD 3.0PPS specifications.

When only battery powers the system and no external load is connected to the USB OTGport, BQ25713/BQ25713B supports the Vmin Active Protection(VAP) feature, in which the device charges up the VBUS voltage from the battery to store someenergy in the input decoupling capacitors. During the system peak power spike, the huge currentdrawing from the battery creates a larger voltage drop across the impedance from the battery to thesystem. The energy stored in the input capacitors will supplement the system, to prevent the systemvoltage from dropping below the minimum system voltage and causing the system crash. This VminActive Protection (VAP) is designed to absorb system power peaks during periods of SOC high powerdemand, which is highly recommended by Intel for the platforms with 1S~2S battery.

BQ25713/BQ25713B monitors adapter current, batterycurrent and system power. The flexibly programmed PROCHOT output goesdirectly to CPU for throttle back when needed.
