Toshiba Launches 2.0A USB Ready Li-Ion Battery Charger IC That Fast Charges
Company Leverages its Advanced 0.13um Mixed-Signal Technology to Maximize
Performance, Power, Area and Cost Efficiencies for Rechargeable Battery

SAN JOSE, Calif., Feb. 6, 2013 /PRNewswire/ -- Toshiba America Electronic
Components, Inc. (TAEC)*, a committed leader that collaborates with technology
companies to create breakthrough designs, today launched its first
high-current USB ready Li-Ion battery charger integrated circuit (IC) with a
fast charging current up to 2.0A. Toshiba's new TC7710WBG charger IC is
manufactured in the company's advanced 0.13um mixed-signal process technology
to achieve cost, power and form-factor efficiencies for optimum charging of
batteries used in smartphones and mobile devices.
Today's rechargeable battery technology is lagging behind advancing processor
technology. As such, current charger solutions require users to charge their
smart phones and other mobile devices more frequently, or for longer periods
of time. The Toshiba TC7710WBG charger IC solves this problem through its
efficient switching regulator core that maximizes power efficiency, passive
component sizes and thermal management for heat dissipation.
"Thecharging current capability, efficiency, and form factor of the TC7710WBG
make it ideal for today's battery hungry mobile devices," said Andrew Burt,
vice president of the Analog and Imaging Business Unit, System LSI Groupat
TAEC. "Toshiba will continue to leverage its advanced process technology and
engineering expertise to deliver a family of charger ICs that keep pace with
the unique battery requirements of smartphones and mobile devices, so end
users can experience longer, more productive use time with these products."
The TC7710WBG leverages the Toshiba 0.13um mixed-signal process to achieve one
of the lowest Rdson*Qg characteristics in the industry making the device well
suited for demanding DC-DC converter applications where high-power density is
needed. The new charger IC is designed with a highly efficient DC/DC buck
regulator that handles up to 2.0A of charging current in a compact WCSP25
2.5mm x 2.5mm package. The 3MHz switching frequency is set high to reduce the
passive components value and therefore their form factors, saving board real
estate. The device can reach peak efficiency above 90 percent, again
leveraging the Toshiba 0.13um mixed-signal technology.
Toshiba has designed theTC7710WBG to protect system and battery circuitry.
The input current comes from a 5V USB adaptor and this voltage is delivered to
the Li-Ion battery through the TC7710WBG switching regulator. It not only
steps down the source voltage to the desirable voltage for the battery, but
also controls the charging profiles dynamically to optimize the charging
duration and operation reliability. The device has an I2C interface that
allows various parameter settings such as charging current and profile
selection. The TC7710WBG also supports the USB On-the-Go (OTG) standard to
power a peripheral USB device, (such as a pico projector), from the battery.
Pricing and Availability
The TC7710WBG will begin sampling in March 2013 with pricing at $0.50 in
thousand piece quantity. Mass production is scheduled to begin May 2013.
