SCM1245MF
The SCM1200MF series are high voltage three-phase motor driver ICs in which transistors, pre-driver ICs (MICs), and bootstrap circuits (diodes and resistors) are highly integrated. These products can run on a three-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
