Toshiba Electronics Europe TC78B011FTG

This Three-phase BLDC pre-driver IC is a feature-rich device that incorporates the complete controller and pre-driver for a three-phase BLDC motor. Its sensor less design saves the space and cost of a Hall sensor. The built-in closed loop speed control regulates and maintains the motor’s rotational speed during dynamic power supply fluctuations and load variations. Precise setting of a speed profile can be programmed into the built-in non-volatile memory (NVM). The TC78B011FTG uses sine-wave drive method, reducing vibration and noise.

Key features

• Sensorless design saves the space and cost of a Hall sensor
• Built-in closed-loop speed control with NVM based setting
• Integrated gate driver with 8 selectable levels of gate drive current
• Sinusoidal control method reduces vibrations and noise

Additional features

• Advantages
