资 源 简 介
The MCP2551 is a high-speed CAN, fault-tolerantdevice that serves as the interface between a CANprotocol controller and the physical bus. The MCP2551provides differenTIal transmit and receive capability forthe CAN protocol controller and is fully compaTIble withthe ISO-11898 standard, including 24V requirements. Itwill operate at speeds of up to 1 Mb/s.Typically, each node in a CAN system must have adevice to convert the digital signals generated by aCAN controller to signals suitable for transmission overthe bus cabling (differenTIal output). It also provides abuffer between the CAN controller and the high-voltagespikes that can be generated on the CAN bus byoutside sources (EMI, ESD, electrical transients, etc.).
