bq25720 SMBus Buck-Boost Battery Charge Controller

Texas Instruments bq25720 SMBus Buck-Boost Battery Charge Controller is a synchronous NVDC buck-boost battery charge controller to charge a 1- to 4-cell battery from a wide range of input sources. These sources include a USB adapter, high voltage USB-C Power Delivery (PD) sources, and standard adapters. The NVDC configuration allows the system to be regulated based on battery voltage but not drop below system minimum voltage. The system keeps operating even when the battery is completely discharged or removed. When load power exceeds the input source rating, the battery goes into supplement mode and prevents the system from crashing.
