LTC2875 60V Fault Protected 3.3V or 5V 25kV ESD High Speed CAN FD Transceiver FEATURES DESCRIPTION n Protected from Overvoltage Line Faults to 60V The LTC 2875 is a robust high speed, low power CAN n 3.3V or 5V Supply Voltage transceiver operating on 3.3V or 5V supplies that features n High Speed CAN FD Operation Up to 4Mbps 60V overvoltage fault protection on the data transmis- n 25kV ESD Interface Pins, 8kV All Other Pins sion lines during all modes of operation, including power- n Variable Slew Rate Driver with Active Symmetry down. The maximum data rate has been extended to Control and SPLIT Pin for Low Electromagnetic 4Mbps to support high speed protocols based on the CAN Emission (EME) physical layer. Supports up to 4Mbps CAN with Flexible n Extended Common Mode Range (36V) Data Rate (CAN FD). Enhanced ESD protection allows n Ideal Passive Behavior to CAN Bus with Supply Off these parts to withstand 25kV HBM on the transceiver n Current Limited Drivers and Thermal Shutdown interface pins without latchup or damage. n Power-Up/Down Glitch-Free Driver Outputs Extended 36V input common mode range and high n Micropower Shutdown Mode common mode rejection on the CAN receiver provides n Transmit Data (TXD) Dominant Timeout Function tolerance of large ground loop voltages. A sophisticated n ISO 11898-2 and CAN FD Compliant CAN driver with active symmetry control maintains tight n DeviceNet Compatible control of the common mode voltage for excellent elec- n Up to MP-Grade Available (55C to 125C) tromagnetic emission, while the variable slew rate and n 3mm 3mm 8-Lead DFN and SO-8 Packages split termination support allow additional EME reduction.
