MC73110 Motor Control IC

Description

The MC73110 Motor Control IC provides high performance digital current loop, velocity loop and commutation for brushless DC motors.  This intelligent single-axis drive controller operates in internal velocity profile mode, velocity mode with an external velocity command signal, or torque mode with an external torque signal.

The MC73110 can be operated standalone, using pre-programmed flash-stored parameters, or through the serial port using microprocessor-style commands.

Features: 

  • Control for 3-phase brushless DC motors
  • High performance digital current loop
  • Velocity loop with encoder or tachometer feedback
  • Internal velocity profile generator
  • Sinusoidal or 6-step commutation
  • Field oriented control
  • Hall sensor inputs
  • 6-signal PWM output with shoot-through protection

  • Serial port up to 416 Kbaud
  • Quadrature encoder input up to 10 Mcounts/sec
  • Serial EEProm for onboard flash configuration load
  • High speed index input & capture
  • SPI (synchronous serial interface) command input
  • Emergency stop input
  • 10 kHz velocity loop & commutation rate
  • 20 kHz PWM output rate
  • Compact 64-pin plastic quad flat pack (PQFP)
