The BQ24210DQCT is a 800mA single-input single cell Li-ion solar Battery Charger targeted at space-limited portable applications. The battery is charged in three phases such as conditioning, constant current and constant voltage with an IC thermal protection and safety timer. The charge current value is programmable through an external resistor. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters. The input voltage regulation loop with programmable input voltage regulation threshold make it suitable for charging from alternative power sources, such as solar panel or inductive charging pad. Furthermore, when no input source is present, the IC has a load mode to power peripherals by connecting the battery to the VBUS. Load mode has current limiting function to prevent overload.
