Applications
The MCP2551-I/P serves as the physical layer interface between CAN protocol controllers such as MCP2515 or MCU-integrated CAN peripherals and the differential CAN bus wiring in automotive body control modules, industrial automation networks, and robotics. Its 1 Mbps speed, ±8 kV ESD protection, and fault-tolerant bus states make it a standard choice for OBDII diagnostic adapters, motor drive networks, and building automation controllers operating over the full -40°C to +125°C automotive temperature range.

Frequently Asked Questions
What is the maximum CAN bus data rate supported by MCP2551-I/P?
MCP2551-I/P supports CAN bus data rates from 10 kbps up to 1 Mbps, compliant with the ISO 11898-2 high-speed CAN physical layer standard. At 1 Mbps the transceiver can serve real-time control networks in automotive powertrain and industrial motion control systems where fast deterministic messaging between 2-wire nodes is required.
How does MCP2551-I/P protect against ESD events on the CAN bus lines?
MCP2551-I/P provides ±8 kV ESD protection on both CANH and CANL differential bus pins, meeting the Human Body Model (HBM) requirement for automotive wiring harness environments. This built-in protection eliminates the need for discrete TVS diodes in most designs, reducing BOM cost and simplifying the 8-pin DIP PCB layout in CAN node prototypes.
Can MCP2551-I/P be used with 3.3 V microcontrollers directly?
MCP2551-I/P requires a 4.5 V to 5.5 V supply for its bus driver stage, but its TX and RX logic inputs are compatible with CMOS logic thresholds that accept 3.3 V MCU drive. A level-shifting resistor or 5 V logic buffer is typically needed on the TX line when connecting to a 3.3 V MCU UART-CAN peripheral to ensure reliable high-level detection by the MCP2551-I/P receiver.
For a CAN network with 30 nodes, does MCP2551-I/P meet the bus loading requirements?
MCP2551-I/P is rated to drive up to 112 nodes on a standard 120 Ω terminated CAN bus at 1 Mbps, far exceeding a 30-node network. Each node presents a minimum 45 kΩ differential input impedance, allowing the transceiver to maintain valid bus voltage levels well within the ISO 11898-2 recessive/dominant voltage margins of 2 V and 1.5 V thresholds.
