Overview

The SN65HVD230QDR is a 3.3V CAN transceiver designed for automotive and industrial environments requiring high reliability and low power consumption. It provides differential transmit and receive capability for ISO 11898-compliant networks at data rates up to 1Mbps. The device is qualified for automotive applications and features significant ESD protection exceeding 15kV on the bus pins.

Why Choose This Part

This transceiver operates from a 3V to 3.6V supply, making it compatible with modern 3.3V microcontrollers without needing a separate 5V rail. It features controlled driver output transition times to improve signal quality and includes thermal shutdown protection. Additionally, unpowered nodes do not disturb the bus, ensuring network integrity during partial power-downs.

Applications

Automotive Networking
Used for vehicle bus communication systems that require AEC-Q100 qualification and high reliability.
Industrial Automation
Ideal for DeviceNet or CANopen networks in factory environments where 3.3V supply rails are common.
Battery Powered Systems
Utilizes a 370uA low-current standby mode to preserve power in portable or battery-backed industrial equipment.
Robotics
Facilitates robust communication between motor controllers and central processing units in high-noise environments.

Getting Started

Engineers can evaluate this part using standard 8-pin SOIC breakout boards or by integrating it directly into PCBs following ISO 11898 layout guidelines. Pin 8 (RS) should be configured for the desired mode: ground it for high-speed operation, use a resistor for slope control, or pull it high for standby mode. Ensure 120-ohm termination resistors are placed at the ends of the CAN bus for proper impedance matching.
