FAN54015 Datasheet Usb-compliant Single Cell Li-ion Switching Charger

Manufacturer: Fairchild (now onsemi)

Overview: FAN54015 — USB-Compliant Single-Cell Li-Ion Switching Charger with USB-OTG Boost Regulator October 2013 FAN54015 USB-Compliant Single-Cell Li-Ion Switching Charger with USB-OTG Boost.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The FAN54015 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 3.4 Mbps.

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