Product Description

The MCP2551 is a high-speed CAN transceiver, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard, including 24V requirements. It will operate at speeds of up to 1 Mb/s.

    • Slope control input
    • Supports 1 Mb/s operation
    • Implements ISO-11898 standard physical layerrequirements
    • Suitable for 12V and 24V systems
    • Externally-controlled slope for reduced RFIemissions
    • Permanent dominant detect
    • Low current standby operation
    • High noise immunity due to differential busimplementation

Product Description

The MCP2561/2FD is a Microchip Technology Inc. second generation high-speed CAN transceiver. It offers the same features as the MCP2561/2. Additionally, it guarantees Loop Delay Symmetry in order to support the higher data rates required for CAN FD. The maximum propagation delay was improved to support longer bus length.The device meets the automotive requirements for CAN FD bit rates exceeding 5 Mbps, low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge (ESD). The device family members are MCP2561FD with SPLIT pin & MCP2562FD with VIO pin



      • Optimized for CAN FD (Flexible Data rate) at 2, 5 and 8 Mbps Operation
        • Maximum Propagation Delay: 120 ns
        • Loop Delay Symmetry: -10%/+10% (2 Mbps)
      • Implements ISO-11898-2 and ISO-11898-5 Standard Physical Layer Requirements
      • AEC-Q100 Grade 0
      • Very Low Standby Current (5 μA, typical)
      • VIO Supply Pin to Interface Directly to CAN Controllers and Microcontrollers with 1.8V to 5.5V I/O
      • SPLIT Output Pin to Stabilize Common Mode in Biased Split Termination Schemes
      • CAN Bus Pins are Disconnected when Device is Unpowered
        • An Unpowered Node or Brown-Out Event will Not Load the CAN Bus
      • Detection of Ground Fault:
        • Permanent Dominant Detection on TXD
