Microchip’s dsPIC33CH family of digital signal controllers (DSCs) feature dual 90 & 100 MIPS 16-bit dsPIC® DSC cores 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 enable the design of 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 many high-performance general-purpose and robust applications.
The dsPIC33CH product family has many features thathelp simplify functional safety certifications for ASIL-B and ASIL-Cfocused applications including: • Functional Safety Manual, FMEDA andDiagnostic Software available under NDA upon request to your local salesoffice• Learn more about 16-bitFunctional Safety capabilities includinghardware, software, and supporting collateral
