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 (MCE

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.
