MCP2551

High-Speed CAN Transceiver

The MCP2551 is a high-speed Controller Area Network (CAN), fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 device 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.

Typically, each node in a CAN system must have a device to convert the digital signals generated by a CAN controller to signals suitable for transmission over the bus cabling (differential output). It also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources (EMI, ESD, electrical transients, etc.).

Features :

• Slope control input

• Implements ISO-11898 standard physical layer requirements
  
• Suitable for 12V and 24V systems
  
• Externally-controlled slope for reduced RF emissions
  
• Permanent dominant detect
  
• Low current standby operation
  
• High noise immunity due to differential bus implementation
