IRMCK143
High Performance Sensorless Motor Control IC
Description
IRMCK171 is a high performance One Time Programmable ROM based motion control IC designed and
optimized for appliance control which contains two computation engines integrated into one monolithic chip.
One is the Flexible Motion Control Engine (MCE
TM
) 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. IRMCK143 comes in a 64 pin QFP package.

IRMCK143
1 Overview
IRMCK143 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 IRMCK143 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. IRMCK143 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. 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 IRMCK143.
IRMCK143 contains 32K bytes of OTP program ROM, The IRMCF143 contains 64K
bytes of Flash and intended for development purposes only while the IRMCK143 is
intended for volume production. Both the development and ROM versions come in a 64-
pin QFP package with identical pin configuration to facilitate PC board layout and
transition to mass production.
