Overview

The MCP2558FDT-H/MNY is a high-speed CAN FD transceiver designed for high-temperature applications, supporting data rates up to 8 Mbps. It serves as the interface between a CAN protocol controller and the physical two-wire CAN bus, providing differential transmit and receive capability. This part is specifically rated for operation up to 150 degrees Celsius, making it suitable for demanding automotive and industrial environments.

Why Choose This Part

This transceiver features an extremely low standby current of 7 uA and includes a Silent Mode to disable the transmitter for bus monitoring. It provides robust protection with integrated thermal shutdown and permanent dominant detection to prevent bus hang-ups. The small 2x3 mm TDFN package helps save board space while maintaining excellent thermal performance up to 150 degrees Celsius.

Applications

Automotive Engine Control
Reliable communication within high-temperature engine compartments and powertrain systems.
Industrial Automation
Robust data networking for factory floor machinery and motor control systems requiring CAN FD speeds.
Aerospace Systems
Used in flight control and sensor networking where wide temperature swings and noise immunity are critical.
Medical Equipment
High-reliability data links for diagnostic and surgical robotics using the CAN FD protocol.

Getting Started

Engineers can evaluate this transceiver using Microchip development boards like the CAN FD Splice Board or by interfacing it with PIC32 and dsPIC33 DSCs that feature integrated CAN FD controllers. Ensure the VDD supply is between 4.5V and 5.5V, and note that the digital I/O level shifter supports logic voltages as low as 1.7V for direct interfacing with low-voltage MCUs.
