SCM1274MF

The SCM1270MF series are high voltage 3-phase motor drivers in which transistors, pre-drive circuits, and bootstrap circuits (diodes and resistors) are highly integrated.
These products can run on a 3-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
