Additional preview pages of the RT9455 datasheet.

The RT9455 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for portable applications.

USB On-The-Go (OTG). The RT9455 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 can be programmed via the I2C interface. The RT9455 resumes the charge cycle whenever the battery voltage falls below an internal threshold and automatically enters sleep mode when the input power supply is removed. Other features include under-voltage protection, ove.
