Description

IRMCS3041 is a reference design for IRMCF341, which is a high performance RAM based motion control IC designed

primarily for appliance applications. It’s mainly aimed to achieve simple, low cost and high performance solutions for

advanced appliance motor control. The system contains an integrated power module, IRAMS10UP60B, which is also a part

of iMOTION

spending development effort usually required in the traditional DSP or microcontroller based system. The complete B/Ms,

schematics and layout are provided so that the user can adapt and tailor the design per application needs.
