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

Control Engine (MCE

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.
