FAN54300 — USB-Compliant, Dual-Power Input, Single-Cell,  
Li-Ion Switching Charger with USB-OTG Boost Regulator  
Description  
Features  
The FAN54300 combines two highly integrated switch-mode  
chargers and a boost regulator to minimize single-cell Li-Ion  
charging time from a USB and/or auxiliary power source.  
. Fully Integrated, High-Efficiency Charger for Single-Cell  
Li-Ion and Li-Polymer Battery Packs  
. Accepts USB or Dedicated Power Input Source  
Charging parameters and operating modes are programmable  
through an I2C Bus® interface that operates up to 3.4 Mbps.  
The charger and boost regulator circuits switch at 3 MHz to  
minimize the size of the external passive components.  
. 5 V, 300 mA Boost Mode for USB OTG from 2.5 to 4.5 V  
Battery Input  
. Charge Voltage Accuracy: 0.5% at TA=25°C  
1% from TA=0 to 125°C  
The FAN54300 provides battery charging in three phases:  
conditioning, constant current, and constant voltage.  
. 5% USB Input Current Regulation Accuracy  
. 5% Charge Current Regulation Accuracy  
. 20 V Absolute Maximum Input Voltage  
To ensure USB compliance and minimize charging time, the  
USB 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.  
. 9.5 V Maximum Input Operating Voltage on VIN Pin,  
6.5 V Maximum on VBUS Pin  
The 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.  
. Up to 1.5 A Maximum Charge Rate  
. Programmable Charge and Mode through High-Speed I2C  
Interface (3.4 Mb/s) with Fast Mode Plus Compatibility  
– Input Current  
– Fast-Charge / Termination Current  
– Charger Voltage  
The FAN54300 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  
– Termination Enable  
The FAN54300 is available in a 30-bump, 0.4 mm pitch,  
wafer-level, chip-scale package (WLCSP).  
. 3 MHz Synchronous Buck PWM Controller with Wide Duty  
Cycle Range  
Applications  
. Small Footprint, 1 H, External Inductors  
. Safety Timer with Reset Control  
. Cell Phones, Smart Phones, PDAs  
. Digital Cameras  
. Weak Input Sources Accommodated by Reducing  
Charging Current to Maintain Minimum VBUS Voltage  
. Portable Media Players  
. Low Reverse Leakage from Battery Drain to VBUS or VIN  
. Programmable LED Drive for Charge Indication  
. Register and Slave Addresses Compatible with FAN540X  
and FAN542X Families
