Overview

The SN65HVD234QDRQ1 is a 3.3V CAN bus transceiver designed for use in Controller Area Network systems. This AEC-Q100 qualified device serves as the interface between a CAN protocol controller and the physical differential bus, supporting signaling rates up to 1 Mbps. It is specifically engineered for operation in harsh environments, offering robust protection features and a low-power standby mode.

Why Choose This Part

This transceiver operates from a single 3.3V supply, eliminating the need for a 5V rail in modern low-voltage systems. It features high ESD protection up to 16kV HBM and an ultra-low-current sleep mode that draws only 50nA. The device also includes a loop-back mode for self-diagnostic routines and is qualified for automotive applications under AEC-Q100.

Applications

Automotive Body Control
Used in vehicle electronic control units (ECUs) to facilitate communication between sensors and actuators over the CAN bus.
Industrial Automation
Provides reliable data transmission for factory automation networks and programmable logic controllers (PLCs).
Battery Management Systems
Enables high-speed communication between battery cell monitors and the central management unit in electric vehicle powertrains.
Advanced Driver Assistance Systems
Transmits critical data for ADAS sensors and radar modules where automotive-grade reliability is required.

Getting Started

To evaluate this part, use the Texas Instruments TCAN1042DEVM or similar CAN evaluation modules. Ensure the RXD and TXD pins are connected to a 3.3V logic MCU and provide a 120-ohm termination resistor at both ends of the differential bus. Pay close attention to the RS pin configuration to select between high-speed, slope-control, or low-power standby modes.
