The SN65HVD231QDR from Texas Instruments is a robust CAN (Controller Area Network) transceiver that facilitates communication in automotive and industrial applications. This device is designed to interface between a CAN protocol controller and the physical two-wire CAN bus. It is specifically tailored to meet the ISO 11898-2 High Speed CAN (up to 1 Mbps) physical layer standard.

As a member of the 3.3-V CAN transceiver family, the SN65HVD231QDR operates on a nominal supply voltage of 3.3V and includes cross-wire, over-voltage, and loss-of-ground protection. This makes it resilient in harsh electrical environments and suitable for nodes in a CAN network.

Key Features:

• Compatibility: Meets the requirements of the ISO 11898-2 standard for use in high-speed CAN systems up to 1 Mbps.
• Low Power: Features a low current standby mode which can be controlled via the RS pin for power-sensitive applications.
• Protection: Offers protection against damage due to high-voltage bus conditions, with positive and negative bus fault protection exceeding ±36V.
• Thermal Shutdown: Includes a thermal shutdown feature that prevents the device from overheating and ensures reliable operation.
• Flexible Operation: Supports both 3.3V and 5V mixed supply operations, allowing for versatile integration into various circuit designs.
• Robust Design: Designed for rugged industrial environments, providing bus-pin ESD protection exceeding 16 kV HBM (Human Body Model).

Applications:

• Automotive Networks
• Industrial Automation
• Building Automation
• Medical Equipment
• Heavy Machinery

The SN65HVD231QDR is available in a small 8-pin SOIC package, making it suitable for space-constrained applications. Its reliable performance and comprehensive feature set make it an excellent choice for designers looking to implement CAN communication in systems that require stringent noise immunity and fault protection.
