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^TM chipset. User can readily evaluate high performance sensorless control with MCEDesigner^TM software without
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.
