Product Details
The 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 3.3V 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. 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 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.
Applications
- Isolated CAN Bus Interface
