IMI111T046HXUMA1

IMI111T046HXUMA1 is a 600V/4A iMOTION™ IPM for motor control. MI111T integrates the motor controller, a 3-phase high-voltage, rugged gate driver with integrated bootstrap functionality and six 600V TRENCHSTOP™ IGBTs. Depending on the IGBTs employed in the package, IMI111T covers applications with 600V maximum DC voltage. For a typical fan application using 16kHz PWM rate and 2-phase switching an output power of 50W and 70W can be achieved without the use of a dedicated heatsink. It uses DSO-22 package which minimizes external components count and PCB area and features 2.2mm creepage distance between the high-voltage pads to increase the robustness of the system. The motor controller uses the MCE to create a ready-to-use solution to perform control of a PMSM providing the shortest time to market for any motor system at the lowest system and development cost. Typical applications include small and major home appliances, fans, pumps, compressors and general purpose variable speed drives.
