The LTM®2889 is a complete galvanically-isolated Controller Area Network (CAN) μModule® (micromodule) transceiver. No external components are required – a single supplypowersbothsidesofthe interface throughan integrated, isolatedDC/DCconverter. Separateversionsare available for 3.3V and 5V power supplies. The dual voltage CAN transceiver and the adjustable regulator allow 3.3V or 5V isolated power with either the 3.3V or 5V version. Coupled inductors and an isolation power transformer provide 2500VRMS ofisolationbetweenthe line transceiver and the logic interface. This device is ideal for systems wherethegroundloopisbroken, allowingforlargecommon mode voltage ranges. Communication remains uninterrupted for commonmode transients greaterthan 30kV/μs. Supports up to 4Mbps CAN with Flexible Data Rate (CAN FD). A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply. Enhanced ESD protection allows this part to withstand up to ±25kV Human Body Model (HBM) on the transceiver interface pins and ±10kV HBM across the isolation barrier without latchup or damage.
