Overview

The MCP2542FD-H/SN is a high-speed CAN FD transceiver designed for high-temperature applications, supporting data rates up to 8Mbps. It serves as the interface between a CAN protocol controller and the physical two-wire bus, featuring excellent passive behavior when unpowered to avoid loading the bus. This device is AEC-Q100 Grade 0 qualified, making it suitable for extreme thermal environments up to 150 degrees Celsius.

Why Choose This Part

This transceiver offers a very low standby current of 4uA and integrated protection features including thermal shutdown and ground fault detection. Its compliance with ISO 11898-2:2016 ensures interoperability with the latest CAN FD standards while maintaining a high receiver hysteresis of 200mV for noise robustness.

Applications

Automotive ECUs
Ideal for under-the-hood electronic control units requiring CAN FD communication in high-temperature zones.
Industrial Automation
Used in factory floor sensors and actuators where high electromagnetic immunity and fast data rates are required.
Battery Management Systems
Provides reliable communication between cell monitoring units and the main controller in EV or stationary storage systems.
