CP2615-A02-GMR Datasheet/PDFCP2615-A02-GMR is a high-voltage, isolated CAN bus controller from Control Resources, Inc. It is a complete isolated controller that interfaces to a CAN bus or CAN FD bus. CP2615-A02-GMR accurately and reliably handles voltage variations, noise, and electromagnetic interference (EMI), and provides complete galvanic isolation between the bus-side and control-side within the controller. The potential of a system to malfunction or become disabled is decreased due to the high-voltage isolation and protection. The controller’s superior voltage isolation and protection improves the overall reliability of the system.
Application Field of CP2615-A02-GMR
CP2615-A02-GMR is an ideal solution for applications that require CAN-to-CAN bus isolation or multiple transceiver nodes in a single platform. It is especially suitable for equipment or machinery in harsh environment, such as extreme temperatures, industrial robotics, automated factory-floor systems, and variety of automotive infotainment applications. The controller is able to operate in alternating current (AC) or direct current (DC) environments ranging between 20V and 775V, with robust protection against electro-static discharges and surges.
Working Principle of CP2615-A02-GMR
The CP2615-A02-GMR provides reliable galvanic isolation between the bus-side and control-side transceivers and power domains. The controller allows the passage of data while blocking stray DC of unwanted signals, and enables communication between multiple nodes on the CAN bus. The main working principle involves the exchange of proper CAN messages with correct CAN identifiers. The controller follows the CAN specification (such as ISO 11898-2 in the case of CAN bus) and operates according to the rules. If the messages transmitted pass the test and contain the correct identifiers, then communication between the accessed nodes on the bus is established. Since the controller has a built-in 60 μsec isolation, it is capable of isolating and protecting the erratic messages and noise. Apart from protection and isolation, the controller also provides automatic rest and acknowledge output signals.
Conclusion
CP2615-A02-GMR is an isolated CAN bus controller from Control Resources, Inc. It provides reliable galvanic isolation between the bus-side and control-side transceivers and power domains, and is ideally suited for applications that require CAN-to-CAN bus isolation or multiple transceiver nodes in a single platform. The isolated CAN bus controller accurately and reliably handles voltage variations, noise and EMI, as well as providing automatic reset and acknowledge output signals. As such, CP2615-A02-GMR is a reliable and versatile controller for applications in harsh environments.
