RT9470D Datasheet 3a Single Cell Switching Battery Charger

Manufacturer: Richtek

Overview: RT9470/D 3A Single Cell Switching Battery Charger 1 General.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The RT9470/D is a highly-integrated 3A switch mode battery charge management and system power path management device for single cell Li-Ion and Li-Polymer batteries.

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.
