General Description

The RT9471/D is a highly-integrated 3A switch mode battery charge management, and system power path management device for single cell Li-Ion and LiPolymer batteries.

The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during the discharging phase.

The I2C serial interface with charging and system settings makes the device a truly flexible solution.
