The TC78B009FTG is a three-phase brushless motor control pre-driver IC that does not require Hall sensors. Designed for applications that include high-speed fans used in servers, blowers, cordless vacuum cleaners, and robot vacuum cleaners.

A built-in closed-loop speed control function regulates and maintains the motor rotational speed under dynamic power fluctuations and load variations.

Precise setting of a speed profile is done by the built-in non-volatile memory (NVM) and the TC78B009FTG therefore eliminates the need for an external MCU for closed-loop speed control.

 

Key features

  • Sensorless Drive
  • NVM-Based Integrated Closed-Loop Speed Control
  • Integrated Gate Driver Supporting 8 Selectable Levels of Gate Drive Current
  • Reduced Noise and Vibration (150° Commutation)

 

Additional features

  • Rotational position is detected by the induced voltage. No hall sensor and less cabling required
  • Regulates motor speed during torque load changes without an MCU
  • Offers flexible choice of external MOSFETs and allows adjusting the FET slew rate

Benefits

  • Reduction of mounting area, cabling and cost (IC & Motor)
  • Constant rotational speed to achieve a constant performance for the use case (i.e. cooling performance in case of a fan). BOM might be reduced as no MCU is required.
  • In a platform approach, the MOSFETs can be dimensioned to match the motor current requirements of a certain product that is based on that platform

Other

  • Reduced size and cost (Sensorless) 
  • Wide range of motor current via external power MOSFET
  • Uniform rotation speeds up to tens of thousands RPM without MCU (closed-loop)
  • Configuration of multiple MCDs via a single I2C bus
  • Current monitor allows real-time adjustments

 

Applications

  • High Velocity Cooling Fans
  • Vacuum Cleaners
  • Pumps
  • Blowers
