SX68120MA/MB Series:
A Guide to Demo Board Evaluation and Phase Advance Angle Tuning
About the SX68120MA/MB Series
The SX68120MA/MB series are high voltage 3-phase motor drivers driven by a sinusoidal control, which can support Hall element and Hall IC inputs, thus offering high-efficient yet low-noise motor control.
Supplied in a package, where a controller, a gate driver, the output transistors of three phases, and bootstrap diodes are highly integrated, the SX68120MA/MB series requires only a few external components for building a motor driver.
This also allows a motor driver to be highly reliable in performance and design-friendly with its compactness.
These products can optimally control the inverter systems of low- to medium-capacity motors that require universal input standards.
