IRMC Series

Überblick

Field-proven solution for motor and PFC control

IRMC motor controller are operating millions of electrical motors around the globe. Driven by Infineon’s Motion Control Engine (MCE) they meet the demand for ever increasing energy efficiency in application areas like home appliances or air conditioning systems. The integrated mature control algorithm for 3-phase motors (PMSM/BLDC) eliminates the need for C programming resulting in a significant reduction of time to market and development cost.

IRMC motor control ICs are offered in several different configurations and packages in order to meet the demands of differing application requirements. The IRMCK099 as the smallest device implements the MCE in a small QFN32 package for applications like fan control. All other IRMC offer an 8-Bit microcontroller based on an 8051 core in addition to the MCE. This combination provides the maximum flexibility for adaptation to customer’s need.

iMOTION™ ICs integrate hardware and software functionality required for controlling PMSM motors with field-oriented control (FOC) (with and without sensors). iMOTION™ products are based on Infineon’s patented, field-tested Motion Control Engine (MCE), which eliminates software coding from the development process. As a result, all users have to do to implement a variable speed drive is configure the MCE for the respective motor drive system.
