Maxim Integrated MAX251CSD+ Isolated CAN Transceiver

The Maxim Integrated MAX251CSD+ is a high-performance, isolated Controller Area Network (CAN) transceiver that provides reliable communication in industrial, automotive, and medical applications. This device ensures robust data transmission with its integrated isolation, which protects against noise, transient voltages, and ground loops that can be common in harsh environments.

The MAX251CSD+ comes in a compact 14-pin SOP package, making it an ideal choice for space-constrained applications. It is designed to interface between a CAN protocol controller and the physical two-wire CAN bus. The transceiver is capable of withstanding voltages up to 2500V RMS for 1 minute per UL1577, providing the necessary isolation for critical applications where safety and reliability are paramount.

With a wide operating temperature range of -40°C to +85°C, the MAX251CSD+ is built to perform reliably in extreme conditions. This transceiver also features a slew-rate-limited driver that reduces EMI and reflections, allowing for stable and clear communication over the CAN network.

Key features of the MAX251CSD+ include:

• Integrated isolation for protection against high voltage and noise
• Compliance with ISO 11898 standards
• Data rates up to 1Mbps for efficient communication
• Thermal shutdown and short-circuit protection for enhanced safety
• Current limiting and power-on reset for robust operation
• Low-current standby mode for power conservation

The device is also designed with a dominant time-out feature that prevents the bus lines from being driven indefinitely in the dominant state, thus ensuring network integrity. The MAX251CSD+ is a powerful solution for designers looking for a reliable, isolated CAN transceiver that can withstand the rigors of industrial environments while maintaining precise and secure data communication.

Whether you are developing applications for industrial control systems, automotive networks, or medical equipment, the Maxim Integrated MAX251CSD+ provides the high level of performance and protection needed to ensure the integrity and reliability of your CAN communications.
