Microchip’s dsPIC33CK family of digital signal controllers (DSCs) features a single 100 MIPS 16-bit dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. These DSCs enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation and provide extended motor life. They can be used to control BLDC, PMSM, ACIM, SR and stepper motors. These DSCs are also ideal for switched mode power supplies such as AC/DC, DC/DC, UPS and PFC, providing high-precision digital control of Buck, Boost, Fly-Back, Half-Bridge, Full-Bridge, LLC and other power circuits to reach the highest possible energy efficiency. These devices are also ideal for high-performance general-purpose and robust applications.
The dsPIC33CK productfamily has many features that help simplify functional safety certificationsfor ASIL-B and ASIL-C focused applications including: • Functional Safety Manual, FMEDA and DiagnosticSoftware available under NDA upon request to your local sales office• Learn more about 16-bit Functional Safety capabilities including hardware, software,and supporting collateral
