2 / 31 page IRMCK099M 1 www.irf.com © 2014 International Rectifier December 18, 2014 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. Features TinyMCE (Tiny Motion Control Engine) - Dedicated computation engine for high efficiency sinusoidal sensorless motor control Internal Oscillator – no clock required Built-in hardware peripheral for single or two shunt current feedback reconstruction and analog circuits Supports both interior and surface permanent magnet motor sensorless control Loss minimization Space Vector PWM Internal ITRIP comparator Two-channel analog output (Sigma Delta D/A) JTAG programming port for debugging UART and I2C serial interface Factory Calibrated Analog Inputs Capture input Watchdog timer with independent internal clock Standby low power mode Internal 16 Kbyte OTP memory CRC Memory Check 3.3V single supply Product Summary Internal clock frequency (SYSCLK) 100MHz MCE TM computation time 1 SYSCLK MCE TM computation data range 16 bit signed OTP Memory 16KB MCE Data RAM 1.5KB MCE Program RAM 12KB FAULT latency (digital filtered) 2 μsec PWM carrier frequency 1 – 20kHz A/D input channels 6 A/D converter resolution 12 bits A/D converter conversion speed 2 μsec Analog output (PWM) resolution 8 bits UART baud rate (typ) 57.6 Kbps Number of digital I/O (max) 8 Package (lead free) QFN 5x5 32L Typical 3.3V operating current < 30mA Standyby mode power consumption 3.5mW Integrated Temperature Sensor(typ) ±5degC Base Part Number Package Type Standard Pack Orderable Part Number Form Quantity IRMCK099M QFN32 Tape and Reel 3000 IRMCK099MTR Tray 2450 IRMCK099M |
