High Efficiency Isolated CAN & Profibus Interface Reference Design
Description
The high-efficiency isolated CAN and Profibus interface reference design is intended for use in industrial systems that require isolated power for CAN and/or Profibus transceivers. This design highlights the ability to completely shut off both the power converter and data transceivers with just one GPIO signal from a microcontroller (when dropping into low-power modes: for example). This isolated interface delivers accurately regulated rails for both primary and secondary power to our Profibus and CAN transceivers without costly opto-coupler feedback circuits making this a simple: efficient and flexible isolated interface for industrial automation. This reference design has the additional feature of allowing the MCU to wait until power is good before transmitting data or to stop transmitting data if a power fault has occured on the interface.The Tiva C Series Launch Pad form factor of this reference design allows easy connection to the LaunchPad board for use of the Tiva C microcontroller in handling the communications protocol to the interface.
Features
- Enable: soft-start and fault functions of TPS55010 provide full MCU control of the power supply rails to the communications interface to maximize system power savingsAdjustable: high-switching frequency increases efficiency: decreases solution size and allows avoidance of sensitive frequency bandsGalvanic insulation technology used in isolated Profibus and CAN transceivers provide proven reliability and stability over time: temperature and moisture
