General Description
The RT9460 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, and high accuracy voltage regulation and charge termination circuits.
Key Features
- USB OnThe-Go (OTG) support. The RT9460 optimizes the charging task by using a control algorithm to vary the charge rate via different modes, including pre-charge mode, fast charge mode, and constant voltage mode. The key charge parameters are programmable via the I2C interface. The RT9460 resumes the charge cycle whenever the battery voltage falls below an internal recharge threshold, and automatically enters sleep mode when the input power supply is removed. Other features include under-voltage.
