Product Details
The LTC2875 is a robust high speed, low power CAN transceiver operating on 3.3V or 5V supplies that features ±60V overvoltage fault protection on the data transmission lines during all modes of operation, including powerdown. 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.
Extended ±36V 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 electromagnetic emission, while the variable slew rate and split termination support allow additional EME reduction.
