MCP2551 High-Speed CAN Protocol Controller

The CJMCU-2551 stands as a high-speed, fault-tolerant CAN device, functioning as a CAN protocol controller and a physical bus interface. The MCP2551 is equipped with a differential receiver for the CAN protocol controller, fully adhering to the ISO-11898 standard, inclusive of the 24V power requirements.It is standard for each node within a CAN system to contain one device. The CAN controller generates a digital signal, which is then transformed into a suitable signal for the transmission bus. Furthermore, it provides a high-voltage buffer between the CAN control device and the CAN bus, which can potentially be impacted by high voltage spikes produced by an external device.

Key Features:

• Supports 1 MB/S operation rate.
• Fulfills ISO-11898 standard physical layer requirements.
• Appropriate for 12V and 24V systems.
• External slope control to minimize RF interference.
• Automatic detection of TXD ground fault input terminal.
• Open reset and brown-out voltage protection.
• A non-powered node or brown-out does not affect the CAN bus.
• Low current standby operation.
• Capability to connect up to 112 nodes.
