FAN54015 Datasheet PDF - Fairchild

Description

●The FAN54010 family (FAN5401X) 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 programmable through an I2C Interface that operates up to 3.4Mbps. The charger and boost regulator circuits switch at 3MHz to minimize the size of external passive components.
