Toshiba Launches Hall Sensorless Sine-Wave Drive Three-Phase Brushless DC Motor Control Pre-Driver IC That Helps to Reduce Vibration and Noise

KAWASAKI, Japan, Feb 8 (Bernama-BUSINESS WIRE) — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a three-phase brushless DC motor control pre-driver IC, “TC78B011FTG,” and started volume shipments today. The product is for high-speed motors, including those used in server fans and blowers, and in the suction motors of cordless and robot vacuum cleaners.

TC78B011FTG 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.
