Microchip Technology's MCP2551 High-Speed CAN Transceiver

The MCP2551 device from Microchip Technology is a high-speed Controller Area Network (CAN) transceiver that serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. This robust transceiver is designed to provide differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard, including 24V requirements.

Key Features

• ISO-11898 Compliant: The MCP2551 meets the requirements of the ISO-11898 standard for use in high-speed CAN systems up to 1 Mbit/s.
• Extended Temperature Range: The device is operational over an industrial temperature range of -40°C to +125°C.
• Protection Features: It includes protection against damage due to short-circuit conditions (positive or negative battery voltage) and also against high-voltage transients in automotive environments.
• High Noise Immunity: Contains features for noise suppression and protection against high-voltage transients, making it ideal for harsh electrical environments.
• Low Current Standby Operation: A low-current standby mode is supported for power-sensitive applications.

Applications

The MCP2551 transceiver is suitable for any CAN network and is particularly well-suited for automotive and industrial applications where high data rates are required. It can be used in a variety of applications such as:

• Automotive networks
• Industrial control systems
• Medical equipment
• Building automation

Technical Specifications

• Supply Voltage: 4.5V to 5.5V
• Standby Current: 5 µA (typical)
• Operating Temperature Range: -40°C to +125°C
• Package Types: 8-pin PDIP, SOIC, and TSSOP

The MCP2551 is a reliable choice for designers looking to implement CAN interfaces in their systems, providing a simple, cost-effective solution that does not compromise on performance or quality.
