TOKYO -- February 7, 2013

Toshiba Corporation (TOKYO: 6502) today announced that it will launch a switch
mode charger IC for lithium-ion battery chargers for mobile devices, such as
smartphones and cellular phones. The new IC, TC7710WBG integrates a detection
circuit compliant with "Battery Charging Spec. Rev. 1.2" and has a maximum
charge current of 2A^[1]. Samples will be available at the end of this month
and mass production is scheduled for May 2013.

The new charger automatically detects USB port type for chargers defined in
"Battery Charging Spec. Rev. 1.2", and restricts input current to efficient
levels such as 100mA, 500mA, etc. Manufacturers can address the IC through the
I^2C interface and change the charge current and voltage, supporting design
charger systems optimized to the specs of product it will be used with. The IC
can also be combined with an external thermistor to detect and automatically
stop charging when temperature exceeds the specified range, a measure that
greatly enhances safety during charging.

[1] Actual charge current depends on the conditions under which the IC is
used, including soldering conditions, thermal resistance conditions, spec of
the lithium-ion battery, etc.

Key Features

1. Built-in detection circuit compliant with Battery Charging Spec. Rev.1.2
2. Temperature detection in combination with an external thermistor.
3. Maximum 2A charge current

Applications

Charger circuit of 1-cell lithium-ion rechargeable batteries for mobile
devices, such as smartphones, cellular phones and tablets.
