SX68200M Series: A Guide to Demo Board Evaluation and Parameter Adjustment
About the SX68200M Series
The SX68200M series are 3-phase brushless motor drivers in which output transistors, pre-drive circuits, bootstrap diodes with current-limiting resistors are highly integrated.
Employing a sinusoidal driving strategy with a sensorless vector control, the SX68200M series brings a small-sized, high-efficient, and low-noise motor controlling into your application.
The products are equipped with a microcontroller, and parameters can be set individually using a dedicated GUI.
For details, please refer to the individual product pages and the datasheets posted there.
