O2Micro International - Optimized Charging of LiIon Batteries
|O2Micro International Brings Optimized Charging to Multiple |
Serial LiIon Batteries
O2Micro International Limited (Nasdaq:OIIM), a leading supplier of innovative
power management ICs to mobile computer and communications
manufacturers, announced the development of an IC for optimized
charging of multiple serial type LiIon batteries. The new IC was
developed in cooperation with Compaq Computer Corp.
"We see this as a major step forward in the reliability and
improved operation of our leading edge notebooks and are glad to lend
our support to this new IC," said Gil Riedesel, director of Options
Technology for Compaq.
This IC is the newest member of O2Micro's family of Intelligent
Power products. The OZ870 IC creates a LiIon battery charger that
fully charges each cell in 3-cell and 4-cell type batteries. Previous
battery charger systems provided current to the entire string of cells
at the battery terminals, which may result in undercharging or
overcharging of one or more battery cells. The OZ870 optimizes
charging of multiple-cell LiIon batteries that result in fully charged
batteries and enhanced user safety. Key features of the part include:
-- Optimized charging of multiple serial type LiIon batteries
-- Increased number of charge-discharge battery cycles
-- Increased reliability
-- Balanced cell-to-cell charging
-- Ensures all cells are fully charged
-- Protects the battery from overcharging of cells
-- Provides previously unavailable cell status information to the
O2Micro Vice President of the Intelligent Power Group, Jack Shyr,
stated, "We are extremely pleased to have worked with the world's
leading PC manufacturer in this product development. Compaq's
extensive system knowledge combined with our mixed signal IC expertise
creates a leading edge IC that will greatly improve the operation of
notebooks and other multi-LiIon cell mobile products."
Founded in March 1995, O2Micro designs, develops and markets
innovative power management and security components for mobile
communication, computer, Internet appliance, and LCD products.
Products include AudioDJ(TM), SmartCardBus(TM) for secure on line
e-commerce, LCD Backlight Inverters and Battery Management ICs.
O2Micro maintains an extensive portfolio of intellectual property
with 205 patent claims granted, and over 300 more pending. The company
maintains offices worldwide. Additional company and product
