dsPIC33E MC Family of Digital Signal Controllers

Motor Control, Real-Time Control, Dual CAN, Functional Safety, Scalable

Electric motors are everywhere, spanning industrial, automotive, consumer and medical applications. Since these electric motors are an integral part of many electrical devices and consume significant power, minimizing power consumption is an essential design consideration. Our dsPIC33E MC family offers 70 MIPS performance, a Digital Signal Processing (DSP) engine and specialized peripherals for implementing high-efficiency, high-precision, variable-speed, constant-torque Proportional Integral (PI) control and Field-Oriented Control (FOC) of motors.

The dsPIC33E MC family is ideal for controlling Permanent Magnet Synchronous Motors (PMSMs), Interior Permanent Magnet (IPM) motors, AC Induction Motors (ACIMs) and Brushless DC (BLDC) motors. Combining the performance of a DSP engine and the simplicity of a microcontroller, dsPIC33EP MC DSCs feature three pairs of motor control Pulse-Width Modulators (PWMs), a high-speed Analog-to-Digital Converter (ADC), op amps and comparators for an optimized design. The high-level of analog integration shrinks form factor and reduces your Bill of Materials (BoM) cost. Offering up to 150°C operation, dsPIC33E MC DSCs facilitate a robust motor control design that withstands harsh environments.

These robust DSCs also feature dedicated peripherals and hardware features to help increase reliability in safety-critical applications, ensuring that your end applications operate as intended, with safe shut down if any exception or issue arises. These AEC Q100 Grade 0 qualified DSCs are also excellent options for automotive applications.
