Product details

CAN transceiver for high-temperature bus nodes

The MCP2557FDT-H/MNY is a single-channel CANbus transceiver from Microchip, rated for operation from -40°C to 150°C — the upper end covers under-hood automotive and industrial sensor nodes where standard 125°C parts hit their derating ceiling. It integrates one driver and one receiver, uses a 4.5V to 5.5V supply rail, and provides 200 mV of receiver hysteresis for noise rejection on the bus.

Package and footprint for tight layouts

Housed in an 8-TDFN (2x3 mm) package with an exposed pad, the part requires a thermal land on the PCB — the datasheet recommends a 1.6 x 1.6 mm pad with four vias to the ground plane for heat sinking. The supply voltage tolerance (4.5V–5.5V) means a 5V nominal rail with ±10% margin stays inside the operating window; no external regulator is needed if the bus-side supply is clean.

Active lifecycle and sourcing posture

Available in Tape & Reel (TR) or Cut Tape (CT) for prototyping; the 8-TDFN package is compatible with standard reflow profiles used for lead-free assemblies.

Frequently asked questions

Is MCP2557FDT-H/MNY compatible with CAN FD?

The evidence lists the protocol as CANbus, not CAN FD. For CAN FD operation, check the MCP2562FD or MCP2517FD families — those parts are explicitly rated for flexible data-rate frames.

What is the difference between MCP2557FDT-H/MNY and MCP2551?

The MCP2551 is rated to 125°C maximum; the MCP2557FDT-H/MNY extends that to 150°C. Both are 1/1 driver/receiver CAN transceivers in similar 8-pin packages, but the MCP2557's higher temperature grade suits engine-bay or exhaust-adjacent nodes where the MCP2551 would exceed its junction limit.
