Toshiba TC78B011FTG brushless DC motor control pre-driver IC
Toshiba Electronic Devices & Storage has launched a three-phase brushless DC motor control pre-driver IC, the TC78B011FTG. The product is designed for high-speed motors, including those used in server fans and blowers and in the suction motors of cordless and robot vacuum cleaners.
The device adopts a sine-wave drive method that does not use Hall sensor control. This helps to reduce vibration and noise. 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.
