LTM2889 Isolated CAN FD Module Transceiver and Power FEATURES DESCRIPTION n Isolated 4Mbps CAN FD Transceiver The LTM 2889 is a complete galvanically-isolated Con- n 2500V for 1 Minute Per UL1577 troller Area Network (CAN) Module (micromodule) RMS n Isolated DC Power: 5V (Adjustable to 3.3V) transceiver. No external components are required a n Up to 150mA Available Isolated Power Output single supply powers both sides of the interface through an n 3.3V or 5V Input Supply Voltage Options integrated, isolated DC/DC converter. Separate versions are n UL-CSA Recognized File E151738 available for 3.3V and 5V power supplies. The dual voltage n No External Components Required CAN transceiver and the adjustable regulator allow 3.3V n High Bus Fault Voltage Tolerance: 60V or 5V isolated power with either the 3.3V or 5V version. n Low Power OFF Mode: <1A Typical Coupled inductors and an isolation power transformer n High Common Mode Transient Immunity: 30kV/s provide 2500V of isolation between the line transceiver RMS n Variable Slew Rate Driver with Active Symmetry and the logic interface. This device is ideal for systems Control and SPLIT Pin for Low EME where the ground loop is broken, allowing for large common n Fully ISO 11898-2 and CAN FD Compliant mode voltage ranges. Communication remains uninter- n Ideal Passive Behavior to CAN Bus with Supply Off rupted for common mode transients greater than 30kV/s . n Transmit Data (TXD) Dominant Timeout Function n Supports up to 4Mbps CAN with Flexible Data Rate High ESD: 25kV CANH, CANL to GND2 and V CC2 (CAN FD). A logic supply pin allows easy interfacing with 10kV Across Isolation Barrier n different logic levels from 1.62V to 5.5V, independent of Ambient Operation from 40C to 125C n the main supply. Low Profile 15mm 11.25mm BGA Package Enhanced ESD protection allows this part to withstand up APPLICATIONS to 25kV Human Body Model (HBM) on the transceiver interface pins and 10kV HBM across the isolation barrier n Isolated CAN Bus Interface without latchup or damage. n Industrial Networks L, LT, LTC, LTM, Linear Technology, Module and the Linear logo are registered trademarks of n DeviceNet Applications Analog Devices, Inc.
