General Description

The FAN5400 family (FAN540X) combines a highly integrated switch-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery.

The charging parameters and operating modes are 2 programmable through an I C Interface that operates up to 3.4Mbps.

The charger and boost regulator circuits switch at 3MHz to minimize the size of external passive components.
