Overview
® RT9460 Switch-Mode Single Cell Li-Ion Charger with USB-OTG 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.
Besides, the charging current is regulated through the integrated sensing resistors.
The RT9460 also 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 ...
