Toshiba to Launch Charger IC for Lithium-ion Rechargeable Battery Charge Devices in Mobile Devices

Efficient recharge realized in switch mode with built-in Battery Charging Spec. Rev. 1.2 Detection Circuit

TOKYO — (BUSINESS WIRE) — February 7, 2013Toshiba 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 I2C 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.
