In addition, a built-in closed loop speed control function allows a detailed speed profile to be programmed into the IC’s non-volatile memory (NVM), securing suppression of fluctuations in rotation speeds due to power supply voltage or load fluctuations without any need for an external MCU. This helps to reduce vibration and noise. TC78B011FTG adopts a sine-wave drive method that does not use Hall sensor control. Toshiba: TC78B011FTG, a sine-wave drive three-phase brushless DC motor control pre-driver IC. ![]()
