Typical Application


The LTM2889 is a complete galvanic ally-isolated Controller Area Network (CAN) μModule® (micro module) 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 3.3V 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 of isolation between the line transceiver and the logic interface.
