FAN5400 Family

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

USB-OTG Boost Regulator

Features

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.

Fully Integrated, High-Efficiency Charger for Single-Cell

Li-Ion and Li-Polymer Battery Packs

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

3.4Mbps. 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

20V Absolute Maximum Input Voltage

6V Maximum Input Operating Voltage

1.25A Maximum Charge Rate

The FAN540X 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

(3.4Mb/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.

3MHz Synchronous Buck PWM Controller with Wide

Duty Cycle Range

The FAN540X 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

The FAN540X is available in a 1.96 x 1.87mm, 20-bump,

0.4mm pitch WLCSP package.
