KUALA LUMPUR, Dec 3 -- Toshiba Electronic Devices & Storage Corporation (Toshiba) recently announced ‘TC78B009FTG’, a three-phase brushless motor control pre-driver IC that does not require Hall sensors.
The device, whose mass production shipments have already started, can be applied in servers, blowers, cordless vacuum cleaners and robot vacuum cleaners.
The new TC78B009FTG with sensorless control drives an external FET. It controls the gate driving current of a 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 and TC78B009FTG therefore eliminates the need for an external MCU for closed loop speed control.
