General Description

The RT9466 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.

The charge current is regulated through integrated sensing resistors.

Key Features

USB On-The-Go (OTG) support. The RT9466 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 RT9466 will resume the charge cycle whenever the battery voltage falls below an internal recharge threshold, and can automatically enter sleep mode if the input power supply is removed. Other features.
