FAN54040 — FAN54047

USB-OTG, 1.55 A, Li-Ion Switching Charger with Power

Path and 2.3 A Production Test Support

Description

Features

The FAN5404X family includes I²C controlled 1.55 A USB-

Fully Integrated, High-Efficiency Charger for Single-Cell

Li-Ion and Li-Polymer Battery Packs

compliant switch-mode chargers with power path operation

and USB OTG boost operation. Integrated with the charger,

the IC supports production test mode, which provides 4.2 V

at up to 2.3 A to the system.

Power Path Circuit Ensures Fast System Startup with a

Dead Battery when VBUS is Connected

1.55 A Maximum Charge Current

Float Voltage Accuracy:

To facilitate fast system startup, the IC includes a power

path circuit, which disconnects the battery from the system

rail, ensuring that the system can power up quickly following

a VBUS connection. The power path circuit ensures that the

system rail stays up when the charger is plugged in, even if

the battery is dead or shorted.

0.5% at 25°C

1% from 0 to 125°C

5% Input and Charge Current Regulation Accuracy

Temperature-Sense Input Prevents Auto-Charging for

JEITA Compliance

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.

Thermal Regulation and Shutdown

4.2 V at 2.3 A Production Test Mode

5 V, 500 mA Boost Mode for USB OTG

28 V Absolute Maximum Input Voltage

6 V Maximum Input Operating Voltage

The FAN5404X provides battery charging in three phases:

conditioning, constant current, and constant voltage. The

integrated circuit automatically restarts the charge cycle

when the battery falls below a voltage threshold. If the input

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

blocking battery current from leaking to the input. Charge

status is reported back to the host through the I²C port.

Dynamic input voltage control prevents a weak adapter’s

voltage from collapsing, ensuring charging capability from

such adapters.

The FAN5404X is available in a 25-bump, 0.4 mm pitch,

WLCSP package.
