Frequently Asked Questions

What is the difference between integrated motor drivers and gate drivers?

Integrated motor drivers include power MOSFETs and control logic in one package, providing a complete solution with minimal external components. Best for applications up to 10A and 60V. Gate drivers only provide the low-voltage control signals to drive external MOSFETs, allowing custom power stage design. Best for high-current (>10A) or high-voltage (>60V) applications. MPS offers both - MPQ6541 for integrated and MPQ18021 for gate driver applications.

Choose integrated drivers for quick development under 10A. Choose gate drivers for high-power custom designs.

What motor control algorithms does MPS support?

MPS motor drivers support various control algorithms: 1) Trapezoidal (6-step) - simple, cost-effective control for BLDC motors. 2) Sinusoidal - smoother operation with lower torque ripple. 3) Field-Oriented Control (FOC) - maximum efficiency and dynamic performance. 4) Sensorless - back-EMF detection eliminates position sensors. 5) Sensored - Hall sensor or encoder feedback for precise control. The MPQ6541 supports trapezoidal and sinusoidal, while MPQ6570 supports FOC for high-performance applications.
