MCP2551 High Speed CAN Protocol Controller

The CJMCU-2551 is a fault-tolerant high-speed CAN device, which can be used as a CAN protocol controller and physical bus interface. The MCP2551 provides a differential receiver for the CAN protocol controller and is fully compliant with the ISO-11898 standard, including the 24V power requirements.

Typically, each node in a CAN system should have one device. The CAN controller produces a digital signal that converts into an appropriate signal for the transmission bus. Additionally, it provides a high-pressure buffer between the CAN control device and the CAN bus, which can be affected by high voltage spikes generated by an external device.

Key Features:

• Supports 1 MB/S operation rate.
• Meets ISO-11898 standard physical layer requirements.
• Suitable for 12V and 24V systems. External slope control reduces 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.
• Can connect up to 112 nodes.
