The LTM2889HY-3#PBF is an isolated CAN transceiver from Analog Devices that integrates a 2500Vrms digital isolator and a CAN transceiver into a single 32-BGA module. It is designed for CAN, DeviceNet, and industrial applications where galvanic isolation between the CAN bus and the controller side is required. The module handles both the signal isolation and the bus transceiver function, reducing board area and simplifying compliance with isolation standards.
The 2500Vrms isolation rating is the key spec for this part. It provides reinforced isolation between the CAN bus and the host controller, which is typically required in industrial environments with long bus runs or where ground potential differences exist between nodes. For DeviceNet applications, this isolation simplifies compliance with the DeviceNet physical layer requirements. The isolation is built into the module, so you do not need a separate isolator IC or isolated DC-DC — the LTM2889HY-3#PBF handles both the signal and power isolation internally.
