USB-Powered Li+ Charger  
General Description  
Features  
The MAX1811 is a single-cell lithium-ion (Li+) battery  
charger that can be powered directly from a USB port*  
or from an external supply up to 6.5V. It has a 0.5%  
overall battery regulation voltage accuracy to allow  
maximum utilization of the battery capacity.  
o Charges Single-Cell Li+ Batteries Directly from  
USB Port  
o 0.5% Overall Charging Accuracy  
o Minimal External Components  
o Input Diode Not Required  
The charger uses an internal FET to deliver up to  
500mA charging current to the battery. The device can  
be configured for either a 4.1V or 4.2V battery, using  
the SELV input. The SELI input sets the charge current  
to either 100mA or 500mA. An open-drain output (CHG)  
indicates charge status.  
o Automatic IC Thermal Regulation  
o Preconditions Near-Depleted Cells  
o Convenient Power SO-8 Package (1.4W)  
o Protected by U.S. Patent # 6,507,172  
The MAX1811 has preconditioning that soft-starts a  
near-dead battery cell before charging. Other safety  
features include continuous monitoring of voltage and  
current and initial checking for fault conditions before  
charging.  
The MAX1811 is available in a small 1.4W thermally  
enhanced 8-pin SO package.
