BQ24190EVM-021 Datasheet PDF - TI

The BQ24190EVM-021 is a complete charger module for evaluating an I2C controlled single NVDC-1 charge using the BQ24190 device. The bq24190 is a highly integrated switch mode battery charge management and system power path management devices for single cell Li ion and Li polymer battery in a wide range of tablet and other portable devices. Its low impedance power path optimizes switch mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution. The device supports a wide range of input sources, including standard USB host port, USB charging port and high power DC adapter.
