Toshiba Launches Industry's Lowest ON Resistance 8.5mΩ Load Switch ICs with Reverse Current Blocking and Thermal Shutdown Circuits

TOKYO — (BUSINESS WIRE) — December 4, 2013Toshiba Corporation (TOKYO:6502) today announced the launch of load switch ICs embedded with reverse current blocking circuits[1] and thermal shutdown circuits[2] that offer an ON resistance of 8.5mΩ[3], the industry’s lowest[4]. The ICs are suited for use as power management switches in smartphones, tablets, Ultrabooks™ and other mobile devices. Samples shipment starts from today with mass production scheduled for spring 2014.

The new products, TCK111G and TCK112G, achieve low ON resistance and low operating voltage in a 1.0mm x 1.5mm compact package by adopting Toshiba's unique CMOS process and analog circuit design techniques. As smartphones, tablets, Ultrabooks and other mobile devices require longer battery hours, lighter weight and smaller size, there is increasing demand for ultra-compact, low power consumption, low power dissipation switches.

Toshiba will increase its line-up of compact, high performance load switch IC to meet the requirements of the rapidly increasing mobile equipment market, with devices suitable for other markets also in the pipeline.

Applications

Power management switches for smartphones, tablets, Ultrabooks and other mobile devices.
