SN65HVD252DR CAN Transceiver from Texas Instruments

The SN65HVD252DR is a robust, high-performance Controller Area Network (CAN) transceiver from Texas Instruments designed to facilitate communication in automotive and industrial applications. This device serves as an interface between a CAN protocol controller and the physical two-wire CAN bus, designed to transmit and receive differential signals.

The SN65HVD252DR operates over a wide supply voltage range of 3.0V to 3.6V and can handle bus fault voltages from -27V to +40V, making it highly resilient to electrical disturbances and suitable for harsh environments. It is compliant with the ISO 11898-2 High-Speed CAN physical layer standard, ensuring reliable communication at speeds up to 1 Mbps.

This transceiver features cross-wire, overvoltage, and loss of ground protection from automotive hazards. Additionally, it incorporates thermal shutdown and an open-drain diagnostic output that indicates bus fault conditions, enhancing system reliability. The device also supports silent mode (also known as listen-only mode) which disables the transmitter while allowing the receiver to continue monitoring the bus, useful for nodes that require bus monitoring without influencing the bus traffic.

Key Features:

• Designed for operation in especially harsh environments.
• Low current standby operation with typical current draw of 370 µA.
• Compatible with 3.3V and 5V microcontrollers.
• Bus-pin ESD protection exceeds 16 kV HBM (Human Body Model).
• Power-on reset and voltage brown-out protection.
• Available in a small 8-pin SOIC package, ideal for space-constrained applications.

Applications:

• Automotive networks.
• Industrial automation and control systems.
• Building automation.
• Medical equipment and healthcare systems.

In summary, the SN65HVD252DR from Texas Instruments is an indispensable component for reliable CAN communication in demanding environments. Its protective features and compliance with industry standards make it a preferred choice for designers and engineers looking for a robust communication solution.
