IRMCF183M
High Performance Sensorless Motor Control IC
Description
IRMCF183M is a high performance Flash based motion control IC designed and optimized for low cost appliance
control which contains two computation engines integrated into one monolithic chip. One is the Flexible Motion
TM
Control Engine (MCE ) for sensorless control of permanent magnet motors or induction motors; the other is an
8-bit high-speed microcontroller (8051). The user can program a motion control algorithm by connecting these
control elements using a graphic compiler. Key components of the complex sensorless control algorithms, such
as the Angle Estimator, are provided as complete pre-defined control blocks. A unique analog/digital circuit and
algorithm fully supports single shunt or leg shunt current reconstruction. IRMCF183M comes in a 32 pin 5x5 QFN
package.

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
TM
using the unique flexible Motion Control Engine (MCE ) for permanent magnet motors as well as
TM
induction motors. The MCE
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
TM
MATLAB/Simulink 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.
