The bq24210 device is a highly integrated Li-Ion linear charger targeted at space-limited
portable applications. The battery is charged in three phases: 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.
