RT9467 - 5A Single Cell Li-Ion Switching Battery Charger

Datasheet Summary

Description

The RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for portable applications.

It integrates a synchronous PWM controller, power MOSFETs, input current sensing and regulation, high-accuracy voltage regulation, and charge termination.

Features

  • USB On-The-Go (OTG) support. RT9467 integrates D+/D- pin for USB host/charging port detection. The RT9467 optimizes for charging task by using a control algorithm to vary the charge rate for different modes, including pre-charge mode, fast charge mode (constant voltage and constant current). The key charge parameters are programmable through an I2C interface. The RT9467 will resume the charge cycle whenever the battery voltage falls below an internal recharge threshold, and can automatically ent.
