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.
