MCP2551-I/P Microchip IC, Can Transceiver, Dip8, 2551 , Integrated Circuit

The MCP2551-I/P is a high speed CAN, fault tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551-I/P 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 1Mb/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.).

• Supports 1Mb/s operation
• Implements ISO-11898 standard physical layer requirements
• Suitable for 12V and 24V systems
• Externally controlled slope for reduced RFI emissions
• Detection of ground fault (permanent Dominant) on TXD input
• Power-on Reset and voltage brown-out protection
• An unpowered node or brown-out event will not disturb the CAN bus
• Low current standby operation
• Protection against damage due to short-circuit conditions (positive or negative battery voltage)
• Protection against high voltage transients
• Automatic thermal shutdown protection
• Up to 112 nodes can be connected
• High noise immunity due to differential bus implementation
