This 3-phase brushless motor control pre drive IC does not require Hall sensors and is suitable for many applications such as servers, blowers, cordless vacuum cleaners, robot vacuum cleaners, etc. that use high-speed fans. The new TC78B009FTG, which adopts sensorless control technology, can drive external FETs. It can control the gate driving current of FETs and can be used in conjunction with various types of FETs. In addition, the closed-loop speed control function can adjust and maintain the motor speed in the event of dynamic power fluctuations and load changes. The precise setting of speed is achieved through the built-in non-volatile memory (NVM), so TC78B009FTG can achieve closed-loop speed control without the need for an external MCU.
