KAWASAKI, JAPAN – (BUSINESS WIRE) – January 12, 2022 –

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has introduced the “TCK12xBG Series” of load transformer phasing which provides a remarkable reduction in quiescent current. [1] The rated output current is 1A. The new integrated circuits, contained in the small WCSP4G package, will support product developers in creating a new generation of wearable devices and IoT devices that consume less power and provide a longer charging life. Volume shipments start today.

The TCK12xBG series uses a new driver circuit, which achieves a typical ON-state quiescent current of 0.08nA [1]. This is an area decrease of 99.9% from Toshiba’s current “TCK107AG” product, and is a major efficiency advance that will allow wearables and IoT devices powered by small batteries to operate for much longer.

WCSP4G, a new developed product package, is approximately 34% smaller than the TCK107AG, only 0.645 x 0.645 mm, allowing installation on small panels. Its back coating can reduce the damage that can occur to such a microchip in the installation process.

Toshiba has prepared a set of three integrated circuits: TCK127BG with automatic discharge triggered at active height; TCK126BG without automatic discharge operating at active altitude; The TCK128BG with automatic discharge is triggered at an active low level. This gives product developers and designers the freedom to choose the IC load switch that best suits their design requirements.

Toshiba will continue to enhance its existing quiet low-tech products, to contribute to downsizing equipment, reducing energy consumption, and achieving a sustainable future.

Applications

  • Wearable devices, IoT devices, smartphones (power supply on and off switch for sensors, etc.)
  • Replacing load switching circuits composed of discrete semiconductors such as MOSFETs, transistors, etc.

Features

  • Ultra Quiet Low Current (On Condition) [1]: IQ = 0.08nA (Type)
  • Low Standby Current (Off Condition): IQ (Off) + I SD (Off) = 13nA (Type)
  • WCSP4G Compact Package: 0.645 x 0.645 mm (type), Ton: 0.465 mm (max.)
  • Back coating reduces damage in the panel installation process

Noticeable:

[1] Among the load switch ICs, a compressed package size of 1 mm2 or less and a current output rate of 1A are included. Toshiba survey, as of January 2022.
