Industrial drive control SoC accepts digital & analogue sensor inputs
Positioned as the first on-chip solution supporting both analogue and digital position sensors, TMS320F28379D and TMS320F28379S microcontrollers (MCUs) are an expansion to TI’s C2000 Delfino MCU portfolio and, when combined with DesignDRIVE Position Manager technology, enable simple interfacing to position sensors. System performance is improved by completing the decode tasks on-chip and reducing the communication latency, enabling faster control loop performance. Developers can decrease system cost by reducing the board area required in FPGA or ASIC-based solutions. Position Manager gives developers access to the base functionality needed to interface to EnDat2.2, BiSS-C, Resolver and SIN/COS sensors. Based on the real-time control architecture of TI’s C2000 MCUs, the DesignDRIVE platform is applicable to development of all varieties industrial inverter and servo drives.
DesignDRIVE is a single hardware and software platform to develop and evaluate solutions for a variety of industrial drive and servo topologies. Position Manager, a technology within DesignDRIVE, allows developers to interface with digital and analogue position sensors, and appears for the first time in these two MCUs: it allows industrial drives system designers to eliminate the engineering effort needed to develop, support and maintain the FGPAs or ASICs required to connect to these sensors today. A single C2000 Delfino MCU gains the flexibility to support multiple sensor types. This includes EnDat 2.2, BiSS-C, Resolver, SIN/COS and incremental encoders including Clockwise/Counterclockwise protocols (CW/CCW).
TI worked with position sensor developer Heidenhain to test this on-chip solution to ensure compatibility. “We approve of Texas Instruments’ successful implementation and testing of Position Manager to our EnDat specifications,” said Herbert Reiter, Heidenhain’s Senior Product Manager.”
The C2000 DesignDRIVE development kit offers exploration of a wide variety of motor drive topologies, as well as easy expansion to develop with real-time Ethernet communications and functional safety topologies.
– DesignDRIVE is supported by TI’s C2000 controlSUITE package and includes specific examples of vector control of motors, incorporating current, speed and position loops.
– Users can download TI’s Code Composer Studio integrated development environment (IDE), providing code generation and debugging capabilities.
– For model-based simulation and software development, TI’s C2000 F28379D and F28379S MCUs are fully compatible with F28377D and F28377S, which are now supported by Mathworks’ Simulink and Embedded Coder.
– Users can download reference interface and power supply designs for motor drives to either use immediately or modify.
Developers can integrate TI’s ISO5852S family of reinforced isolated gate drivers when developing industrial drive power stages. This family delivers the industry’s highest working voltages of up to 1.5 kVrms, highest common mode transient immunity (CMTI) of 100 kV/μsec minimum, and precision timing to efficiently drive high-voltage and fast switching IGBT and SiC power switches. Pricing for this family starts at $2.15 (1,000).
TMS320F28379D and TMS320F28379S MCUs are priced from $17.20 (1000). The DesignDRIVE Kit (TMDXIDDK379D), which includes both the hardware and software, is $999 and are available via the TI Store and authorized distributors. To further ease development, customers can download the Position Manager technology from the DesignDRIVE: videos are at; Position Manager and DesignDRIVE.
