MC3PHAC Monolithic Intelligent
Motor Controller
Overview
The MC3PHAC is a high-performance monolithic intelligent motor controller designed specifically to meet
the requirements for low-cost, variable-speed, 3-phase ac motor control systems. The device is adaptable
and configurable, based on its environment. It contains all of the active functions required to implement
the control portion of an open loop, 3-phase ac motor drive.
One of the unique aspects of this device is that although it is adaptable and configurable based on its
environment, it does not require any software development. This makes the MC3PHAC a perfect fit for
customer applications requiring ac motor control but with limited or no software resources available.
The device features are:
• Volts-per-Hertz speed control
• Digital signal processing (DSP) filtering to enhance speed stability
• 32-bit calculations for high-precision operation
• Internet enabled
• No user software development required for operation
• 6-output pulse-width modulator (PWM)
• 3-phase waveform generation
• 4-channel analog-to-digital converter (ADC)
• User configurable for standalone or hosted operation
• Dynamic bus ripple cancellation
• Selectable PWM polarity and frequency
• Selectable 50/60 Hz base frequency
• Phase-lock loop (PLL) based system oscillator
• Serial communications interface (SCI)
• Low-power supply voltage detection circuit
Included in the MC3PHAC are protective features consisting of dc bus voltage monitoring and a system
fault input that will immediately disable the PWM module upon detection of a system fault.
