Overview
The LTM2889HY-3#PBF is a complete galvanically-isolated Controller Area Network (CAN) µModule (micromodule) transceiver produced by Analog Devices Inc. This device integrates all necessary components for a CAN FD transceiver and isolated power supply, eliminating the need for external components. It features a single supply that powers both sides of the interface through an integrated, isolated DC/DC converter. The LTM2889HY-3#PBF is available in versions supporting 3.3V and 5V power supplies, with adjustable regulators to provide isolated power at either voltage level.
