Description

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
