IRMCF183M
1 Overview
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^TM) for permanent magnet motors as well as
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^TM development environment. Sequencing, user interface, host communication, and
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.
