SCM1272MA

The SCM1272MA is a high voltage 3-phase motor driver in which transistors, pre-drive circuits, and bootstrap diodes with current-limiting resistors are highly integrated. 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.
