Green Motion Controller (MCGP02I)


Green Motion Controller (MCGP02I) is a high performance, general purpose motion control IC providing field oriented control (FOC) for permanent magnet synchronous motors (PMSM). It frees the host processor for other tasks by performing all the time-intensive digital signal processing (DSP) functions of the FOC. The programmability of all control parameters enables maximum flexibility and quick design of control systems. With an integrated on-chip oscillator, ADC's, voltage references and regulator, the complete control system can be constructed with minimum number of components, thus reducing the PCB real estate as well as overall system cost. A complete control system using MCGP02I can be comprised of merely a host processor to specify commands via SPI, a pair of fully differential amplifiers, a 3 phase PWM motor driver and a PMSM with incremental and UVW encoders. No other costly components like ADC's, voltage references and oscillator are necessary.

Features:

  • Field Oriented Control
  • Torque and Velocity Control
  • PI controllers with saturation and anti-windup for current and velocity loops
  • Single 3.3V supply, comes with on-chip 1.8V regulator for digital circuits
  • On-chip oscillator eliminates the need for external oscillator
  • Two on-chip 10bits ADC for simultaneous sampling of phase A and B currents
  • On-chip voltage references for ADC and Common Mode Voltage
  • Programmable PWM frequency
  • Programmable Velocity loop sampling rate
  • On the fly programmable speed and torque references
  • SPI serial interface
