TOKYO--(BUSINESS WIRE)--Dec 3, 2019--

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced “TC78B009FTG,” a three-phase brushless motor control pre-driver IC that does not require Hall sensors, for applications that include high-speed fans used in servers, blowers, cordless vacuum cleaners, and robot vacuum cleaners. Mass production shipments start today.

In recent years, advances in server capacity and performance require larger and higher velocity fans for cooling the excess heat generated by the equipment. Similarly, blowers, vacuum cleaners and pumps also operate with high-speed impellers that require a power capability. Consequently, fan driver ICs need to be able to drive an external FET to deliver more power.

The new TC78B009FTG with sensorless control drives an external FET. It controls the gate driving current of an FET, and can be used with various FETs. In addition, a closed loop speed control regulates and maintains the motor rotational speed under dynamic power fluctuations and load variations. Precise setting of a speed profile is done by the built-in non-volatile memory (NVM) and TC78B009FTG therefore eliminates the need for an external MCU for closed loop speed control.
