IRMCF183M is a new generation International Rectifier integrated circuit device primarily designed as a

one-chip solution for complete inverter controlled appliance motor control applications. Unlike a traditional

microcontroller or DSP, the IRMCF183M provides a built-in closed loop sensorless control algorithm

using the unique flexible Motion Control Engine (MCE

induction motors.

The MCE

TM

consists of a collection of control elements, motion peripherals, a

dedicated motion control sequencer and dual port RAM to map internal signal nodes. IRMCF183M also

employs a unique single shunt current reconstruction circuit in addition to two leg shunt current sensing

circuit to eliminate additional analog/digital circuitry and enables a direct shunt resistor interface to the IC.

Motion control programming is achieved using a dedicated graphical compiler integrated into the

MATLAB/Simulink

upper layer control tasks can be implemented in the 8051 high-speed 8-bit microcontroller. The 8051

microcontroller is equipped with a JTAG port to facilitate emulation and debugging tools. Figure 1 shows

a typical application schematic using the IRMCF183M.

IRMCF183M is available in a 32-pin QFN package.
