LTC2875MPS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC2875MPS8#PBF is a high-speed CAN FD transceiver manufactured by Analog Devices Inc. It operates on 3V to 5.5V supplies and supports data rates up to 4Mbps. The device features ±60V overvoltage fault protection on the bus lines during all modes, including power-down. It provides ±25kV ESD protection on interface pins and an extended common mode range of ±36V at 5V supply. Operating temperature ranges from -55°C to +125°C. It utilizes an SO-8 package with one driver and one receiver.

Drivers, Receivers, Transceivers FAQ

How does the device handle ground open faults?

The LTC2875 protects itself from damage during VCC open or shorted-to-GND conditions. However, if GND is open while VCC is present, designers must ensure input drivers are protected against shorts to VCC - 2.5V to prevent sneak paths.

What is the purpose of the SPLIT pin?

The SPLIT pin provides a common mode stabilization output for optional split termination. It helps maintain tight control of the common mode voltage to reduce electromagnetic emissions.

Can the LTC2875 operate with mixed supply voltages on the same bus?

Yes, it can share a bus with 5V transceivers. However, mixing 3.3V and 5V supplies may increase electromagnetic emissions due to fluctuations in common mode voltage between 1.95V and 2.5V.
