Dual Channel Sensorless PM Motor Control IC

IRMCF312 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF312 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance Motor Control TM IRMCF312 contains two computation engines. One is Motion Control Engine (MCE ) for sensorless control of permanent magnet motors; the other is an 8-bit high-speed Microcontroller (8051). Both computation engines are integrated into one TM monolithic chip. The MCE contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user CAN program a motion control algorithm by connecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique Analog/Digital circuit and algorithm to fully support single shunt current reconstruction is also provided. The 8051 Microcontroller performs 2- cycle instruction execution (60MIPS at 120MHz). The MCE and 8051 Microcontroller are connected via dual port RAM to TM process signal monitoring and command input. An advanced graphic compiler for the MCE is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCF312 comes with a small QFP100 pin lead-free package. By International Rectifier Corp.
