Motor drivers

Motor driver technologies

Drive innovation with smarter, safer and smaller motor drivers

Our motor drivers help you easily create more compact applications with smoother motion and better protection. Leverage our integrated solutions with advanced on-chip control algorithms and protection, diagnostic and safety features to maximize motor performance.

Smart gate drivers integrate passive components to reduce board size, design complexity and cost.

Smart tuning reduces power loss and improves thermal dissipation while simplifying design complexity and improving accuracy.

Introduction to smart gate drive

Smart gate drive offers a level of protection and configurability to improve design simplicity and bring a new level of intelligence to motor systems. View the video below to learn more about the benefits and features of smart gate drive technology. 

Key benefits:

  • Reduce system cost: Integrate up to 24 external components typically used in standard gate drivers to reduce PCB size.

 

  • Reliable protection: Design-in MOSFET drain-source and gate-source fault detection to prevent false FET turn-on due to coupling.

 

  • Ease of use: Simplify design with integrated automatic dead-time and programmable gate drive current to optimize EMI.
