SX68201M
The SX68201M is the 3-phase brushless motor driver 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 SX68201M brings a small-sized, high-efficient, and low-noise motor controlling into your application.
The product can run on a 3-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
