RT5081
Highly-Integrated Sub-PMIC for Mobile Applications
General Description
The RT5081 is a highly-integrated smart power management IC, which includes a single cell Li-Ion/LiPolymer switching battery charger, a USB Type-C & Power Delivery (PD) controller, dual Flash LED current sources, a RGB LED driver, a backlight WLED driver, a display bias driver and a general LDO for portable devices.
The switching charger integrates a synchronous PWM controller, power MOSFETs, input current sensing and input current regulation, high-accuracy voltage regulation, and charge termination circuitry. Besides, the charge current is regulated through the integrated sensing resistors. It also features USB On-The-Go (OTG) support.
