Linear Technology's LTM2889 is a complete galvanically isolated controller area network (CAN) μModule (micromodule) transceiver. No external components are required; a single supply powers both sides of the interface through an integrated, isolated DC/DC converter. Separate versions are available for 3.3 V and 5 V power supplies. The dual voltage CAN transceiver and the adjustable regulator allow 3.3 V or 5 V isolated power with either the 3.3 V or 5 V version. Coupled inductors and an isolation power transformer provide 2500 V_RMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken, allowing for large common mode voltage ranges. Communication remains uninterrupted for common mode transients greater than 30 kV / μs. It supports up to 4 Mbps CAN with flexible data rate (CAN FD). A logic supply pin allows easy interfacing with different logic levels from 1.62 V to 5.5 V, independent of the main supply. Enhanced ESD protection allows this part to withstand up to ±25 kV human body model (HBM) on the transceiver interface pins and ±10 kV HBM across the isolation barrier without latch-up or damage.
