Product Summary

The FAN5400UCX is an USB-compliant single-cell li-ion switching charger with USB-OTG boost regulator. It provides battery charging in three phases: conditioning, constant current, and constant voltage. The FAN5400UCX can operate as a boost regulator on command from the system. The boost regulator includes a soft-start that limits inrush current from the battery. The applications of the FAN5400UCX include: Cell Phones, Smart Phones, PDAs, Tablet, Portable Media Players, Gaming Device, Digital Cameras.
