Toshiba TCK12xBG ICs Extend Battery Life in Wearables and Other Battery-Powered Devices


Toshiba has begun shipping the TCK12xBG series load switch ICs, which it says provide significant quiescent current reduction. They are designed for a nominal output current of 1A. As stated, chips in miniature packages WCSP4G “will help developers create a new generation of wearable devices and IoT devices that consume less power and are characterized by increased battery life.”

The TCK12xBG series uses a new circuit design that results in a typical on-state quiescent current of only 0.08 nA. This is about 99.9% less than a similar Toshiba TCK107AG chip.

The new WCSP4G package mentioned above, designed for these ICs, is about 34% smaller than the TCK107AG package. Its dimensions are 0.645 x 0.645 mm. The body is coated to reduce the risk of damage during installation.

The line includes three ICs: TCK127BG with automatic discharge when active high, TCK126BG without automatic discharge and TCK128BG with automatic discharge when active low. This gives product designers and designers the freedom to select the load switch IC that best suits their design requirements.

The list of applications for the TCK12xBG includes wearables, IoT devices, and smartphones.
