信息

The bq25890, bq25892 are highly-integrated 5-A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer battery. The devices support high input voltage fast charging. The 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.
