FAN54010 / FAN54011 / FAN54012 / FAN54013 / FAN54014

USB-Compliant Single-Cell Li-Ion Switching Charger with

USB-OTG Boost Regulator

Features

Description

The FAN54010 family (FAN5401X) combines

a highly

Fully Integrated, High-Efficiency Charger for Single-Cell

Li-Ion and Li-Polymer Battery Packs

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.

Faster Charging than Linear

Charge Voltage Accuracy:

0.5% at 25°C

1% from 0 to 125°C

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

3MHz to minimize the size of external passive components.

5% Input Current Regulation Accuracy

5% Charge Current Regulation Accuracy

20 V Absolute Maximum Input Voltage

6 V Maximum Input Operating Voltage

1.45 A Maximum Charge Rate

The FAN5401X provides battery charging in three phases:

conditioning, constant current, and constant voltage.

To ensure USB compliance and minimize charging time, the

input current is limited to the value set through the I²C host.

Charge termination is determined by a programmable

minimum current level. A safety timer with reset control

provides a safety backup for the I²C host.

Programmable through High-Speed I²C Interface

(3.4 Mb/s) with Fast Mode Plus Compatibility

–

Input Current

The integrated circuit (IC) automatically restarts the charge

cycle when the battery falls below an internal threshold. If the

input source is removed, the IC enters a high-impedance

mode with leakage from the battery to the input prevented.

Charge status is reported back to the host through the I²C

port. Charge current is reduced when the die temperature

reaches 120°C.

Fast-Charge / Termination Current

Termination Enable

3 MHz Synchronous Buck PWM Controller with Wide

Duty Cycle Range

Small Footprint 1H External Inductor

The FAN5401X 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.

Safety Timer with Reset Control

1.8 V Regulated Output from VBUS for Auxiliary Circuits

The FAN5401X is available in a 1.96 x 1.87 mm, 20-bump,

0.4 mm pitch, WLCSP package.

Weak Input Sources Accommodated by Reducing

Charging Current to Maintain Minimum VBUS Voltage

Low Reverse Leakage to Prevent Battery Drain to VBUS

5 V, 500 mA Boost Mode for USB OTG for 3.0 V to

4.5 V Battery Input

Applications

Cell Phones, Smart Phones, PDAs

Tablet, Portable Media Players

Gaming Device, Digital Cameras
