Toshiba announces new three-phase brushless motor control pre-driver IC

Last update: 29/10/2019

KUALA LUMPUR, Oct 29 -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has announced its ‘TC78B027FTG’, a three-phase brushless motor control pre-driver IC with Intelligent Phase Control (InPAC) and Closed Loop Speed Control technologies.

It enables optimum operating efficiency in applications such as high-velocity server fans, blowers and pumps, according to a statement.

InPAC offers high-efficiency drive by synchronising the phases of the driving voltage and current, thereby delivering maximum real power to the loads.

Meanwhile, a closed loop speed control function regulates and maintains the motor rotational speed under dynamic power fluctuations and load variations, a valuable feature for mission-critical applications such as server fans and other cooling applications.

This operation is usually not possible without some kind of compensation, which generally requires significant motor characterisations upfront and operation adjustments in real time to achieve the optimum efficiency throughout the speed range.

TC78B027FTG also features flexibility in various power applications with appropriate external FETs, whereby Various FETs can be used, covering a wide range of low-to-medium power applications.

Toshiba is among the leading general device companies, offering customers and business partners outstanding solutions in discrete semiconductors, system LSIs and HDD. More information at https://toshiba.semicon-storage.com.
