Infineon Technologies AG has launched a new intelligent power module (IPM) motor controller series, designated iMOTION™ IMI110. The series combines the iMOTION Motion Control Engine (MCE) with a three-phase gate driver and 600-V/2-A or 600-V/4-A IGBTs in a compact DSO-22 package. The integrated motor controller series is suitable for motors in small and large household appliances as well as fans and pumps with typically 70 W output power. Depending on the system design, even higher outputs can be achieved.

The field-proven MCE implements highly efficient field-oriented control (FOC) in sensorless motor inverters. The ready-to-use MCE comes with a code-free motor control and integrated scripting. With its software tool, Solution Designer, for easy configuration and tuning, the MCE simplifies the development of highly integrated, function-optimized motor controller systems, enabling fast time-to-market. Furthermore, rapid prototyping of a customer specific iMOTION IPM is enabled via two new control boards for the iMOTION Modular Application Design Kit (MADK).

The IMI110 series offers improved creepage and clearance. The devices also deliver excellent ruggedness and reliability, they are qualified according to HV-H3TRB. Sensorless single-shunt operation, integrated bootstrap diodes, and single-layer PCB design contribute to a reduced bill of materials (BOM). IMI110 devices are pre-certified for applications requiring functional safety to UL/IEC 60730 (Class B) standard. In addition, they offer a full set of protection features in hardware and software.

The iMOTION IMI110 integrated motor controller series can be ordered now in the 600-V/2-A (IMI111T-026H) variant. The 600-V/4-A (IMI111T-046H) variant will be available early in the second quarter 2023.
