The MCP2551 is a high-speed 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:-
Supports 1 Mb/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 Dorninant) 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
