IRMCF588
Dual Motor High Performance Sensorless Control IC
Description
IRMCF588 is a high performance Flash based motion control IC designed and optimized for complete air
conditioner control which contains two kinds of computation engines integrated into one chip. There are two
Motion Control Engines (MCETM) for sensorless control of permanent magnet motors and 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. IRMCF588 performs a PFC (Power
Factor Correction) function in addition to the motor control. IRMCF588 comes in a 100 pin QFP package.

IRMCF588
1 Overview
IRMCF588 is a new generation International Rectifier integrated circuit device primarily designed as a one-chip
solution for complete two motor inverterized appliance motor control applications. Particular application includes a
full DC inverter Air Conditioner which requires two motor sensorless control plus power factor control. Unlike a
traditional microcontroller or DSP, the IRMCF588 provides a built-in two parallel running computation engines for
two closed loop sensorless control algorithm using the unique Flexible Motion Control Engine (MCETM). The
MCETM consists of a collection of control elements, motion peripherals, a dedicated motion control sequencer and
dual port RAM to map internal signal nodes. IRMCF588 also employs a unique single shunt current
reconstruction circuit to eliminate additional analog/digital circuitry and enables a direct shunt resistor interface to
the IC, while still supporting leg shunt current sensing. Motion control programming is achieved using a
dedicated graphical compiler integrated into the MATLAB/SimulinkTM 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.
Figure 1 shows a typical application schematic using the IRMCF588 in leg shunt mode.
IRMCF588 contains 64K bytes of Flash program memory plus 16K bytes of OTP memory and comes in a 100-pin
QFP package.
