Description
IRMCS1071 is a reference design for IRMCK171, which is a high performance 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, IRAM336-025SB, which is also a part of iMOTION^TM
chipset. The 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.
