The bq25892 is a highly integrated switch-mode battery charge management and system power path management device for single-cell Li-ion and Li-polymer batteries used in a variety of smartphones and other portable devices with USB or high-voltage adapters. Its low-impedance power path optimizes switch-mode operating efficiency, reducing battery charge time and extending battery life during the discharge phase. An I2C serial interface for charging and system setup makes this device a truly flexible solution.
