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

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.

The FAN5401X provides battery charging in three phases:

conditioning, constant current, and constant voltage.

To ensure USB compliance and minimize charging time, the

2

input current is limited to the value set through the I C host.

Charge termination is determined by a programmable

minimum current level. A safety timer with reset control

2

provides a safety backup for the I C host.

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 I

2

C

port. Charge current is reduced when the die temperature

reaches 120°C.

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.

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

0.4mm pitch WLCSP package.
