DESCRIPTION

FEATURES

The LTC^®2875 is a robust high speed, low power CAN

transceiver operating on 3.3V or 5V supplies that features

±±6V overvoltage fault protection on the data transmis-

sion lines during all modes of operation, including power-

down. The maximum data rate has been extended to

4Mbps to support high speed protocols based on the CAN

physical layer. Supports up to 4Mbps CAN with Flexible

Data Rate (CAN FD). Enhanced ESD protection allows

these parts to withstand ±25kV HBM on the transceiver

interface pins without latchup or damage.

Protected from Overvoltage Line Faults to ±±6V

3.3V or 5V Supply Voltage

High Speed CAN FD Operation Up to 4Mbps

±25kV ESD Interface Pins, ±8kV All Other Pins

Variable Slew Rate Driver with Active Symmetry

Control and SPLIT Pin for Low Electromagnetic

Emission (EME)

Extended Common Mode Range (±3±V)

Ideal Passive Behavior to CAN Bus with Supply Off

Current Limited Drivers and Thermal Shutdown

Power-Up/Down Glitch-Free Driver Outputs

Micropower Shutdown Mode

Extended ±3±V input common mode range and high

common mode rejection on the CAN receiver provides

tolerance of large ground loop voltages. A sophisticated

CAN driver with active symmetry control maintains tight

control of the common mode voltage for excellent elec-

tromagnetic emission, while the variable slew rate and

split termination support allow additional EME reduction.
