IRMCF188
High Performance Sensorless Motor Control IC
Description
IRMCF188 is a high performance Flash based motion control IC designed and optimized for complete air
conditioner control which contains two computation engines integrated into one monolithic chip. One is the
Flexible Motion Control Engine (MCETM) 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. IRMCF188
performs a PFC (Power Factor Correction) function in addition to the motor control. IRMCF188 comes in a 64 pin
QFP package.

IRMCF188
1 Overview
IRMCF188 is a new generation International Rectifier integrated circuit device primarily designed as a one-chip
solution for complete inverterized appliance motor control applications. Unlike a traditional microcontroller or
DSP, the IRMCF188 provides a built-in closed loop sensorless control algorithm using the unique Flexible Motion
Control Engine (MCETM) for permanent magnet motors as well as induction motors. 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. IRMCF188 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 IRMCF188 in leg shunt mode.
IRMCF188 contains 64K bytes of Flash program memory and comes in a 64-pin QFP package.
