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 (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. IRMCK143 comes in a 64 pin QFP package.
