3 Description

The bq25600C devices are highly-integrated 3.0-A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer battery. The low impedance power path optimizes switch-mode operation efficiency and reduces battery charging time. The I2C serial interface with charging and system settings makes the device a truly flexible solution.
