IRMCK099 Data Sheet iMOTION motor control IC for single motor drive Quality Requirement Category: Industry Features Ready-to-use solution for high efficiency variable speed drives Pre-programmed motion control engine (MCE) Sensor less field oriented control (FOC) of permanent magnet synchronous motors (PMSM) Support for up to 31 sets of motor parameters Current measurement based on single or leg shunt Integrated oscillator, A/D converter, OP amps & comparators Integrated protection features Package: 5x5mm QFN-32 Applications Pumps & fans Drones, multicopters Home appliances Any other PMSM drive Description The IRMCK099 combines the iMOTION motor control engine (MCE) with all peripherals required to realize a complete variable speed drive. The IRMCK099 does not require algorithm programming and can be used in combination with a IPM or a discrete power stage. The MCE implements sensor less field oriented control using single or leg shunt current feedback and uses space vector PWM with sinusoidal signals to provide highest energy efficiency. Data Sheet Please read the Important Notice and Warnings at the end of this document Revision 1.0 www.infineon.com/iMOTION 2014-12-18 IRMCK099M High Performance Sensorless Motor Control IC Description IRMCK099 is a low cost, high performance OTP memory based motion control ASIC designed primarily for appliance applications. IRMCK099 is designed to implement high performance control solutions for advanced inverterized appliance motor control. IRMCK099 contains the flexible Tiny Motion Control Engine (TinyMCE) for sensorless control of permanent magnet motors over the full speed range. The TinyMCE implements sensorless Field Oriented Control using single or leg shunt current feedback by a combination of hardware and IR-supplied firmware elements. Key components of the complex sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks. The ASIC is designed to eliminate external components and reduce cost by including an A/D converter, analog amplifiers, an overcurrent comparator, watchdog timer and internal oscillator. Strong startup and configuration tools get the motor running quickly without any programming. A standby power mode can help to increase overall system efficiency. IRMCK099 comes in a 5mmx5mm, 32 pin QFN package.
