Toshiba launches 2 three-phase brushless motor controller ICs

Last update: 25/04/2019

KUALA LUMPUR, April 25 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has released two, three-phase brushless motor controller ICs, namely ‘TC78B041FNG’ housed in an SSOP30 package and ‘TC78B042FTG’ in a VQFN32 package.

Both adopt InPAC, Toshiba’s original automatic phase adjustment function, to eliminate phase adjustment and achieve high level efficiency at a wide range of motor rotation speeds.

This allows their use with motor drivers of various voltages and current capacities, and they also can be used in combination with intelligent power devices at the output stages.

The use of a sine wave drive system with a smooth current waveform reduces noise, and generates less noise and vibration than motors with a rectangular wave drive system.  

TC78B042FTG adopts a VQFN32 (5mm x 5mm x 1mm) package that can be mounted in limited spaces. The popular SSOP30 package is also available as TC78B041FNG.

Toshiba said the controllers, for which mass production had already started, were suited for use in home appliances such as air-conditioners and air purifiers, and industrial equipment.
