Solutions - Robust 4Mbps CAN FD µModule Isolator with Power Improves System Reliability

MILPITAS, CA – September 13, 2016 – Linear Technology Corporation introduces the LTM2889, a fully ISO 11898-2 compliant CAN (controller area network) µModule® (micromodule) transceiver and isolator that guards against large ground-to-ground differentials and common mode transients in 3.3V or 5V applications. In practical CAN systems, ground potentials vary widely from node to node, often exceeding the tolerable range, which can result in an interruption of communications or destruction of a transceiver. The LTM2889 separates grounds by isolating the CAN transceiver using internal inductive isolation. It implements multiple levels of protection to significantly improve system reliability, including 2,500VRMS of galvanic isolation, ±60V bus voltage fault tolerance, greater than 30kV/µs common mode transient immunity, and ±25kV HBM ESD protection. The LTM2889 requires no external components, ensuring a complete and robust µModule solution for isolated serial data communications.
