Overview

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 battery in a wide range of smartphone and other portable devices with USB or high voltage adaptors. 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.

Features

Support high voltage adaptor to achieve up to 5A chargeing current
Highly integrated solution with the highest efficiency
Input Current Optimizer (ICO) to best utilize the adaptor
ADC to provide system and battery monitoringBoth host control and autonomous charging when the host is not available
Integrated low Rdson battery FET for long battery run time
