Overview

The NCV7446MW0R2G is a dual-channel, high-speed CAN transceiver that integrates two independent physical layer interfaces for CAN FD networks. Designed for automotive and industrial multi-node systems, it supports data rates up to 5 Mbps while maintaining low electromagnetic emissions and high immunity to interference. The device features a very low-power standby mode with bus wake-up capability and is AEC-Q100 qualified for harsh environments.

Why Choose This Part

The NCV7446 provides significant space savings by integrating two transceivers into a compact 4.5x3mm DFNW14 package with wettable flanks for automated optical inspection. It features robust protection including a TxD dominant timeout, thermal shutdown, and short-circuit protection for bus pins to ground and supply voltages up to 5.25V. Its low-power standby mode draws only 10 microamps, making it efficient for battery-sensitive automotive applications.

Applications

Automotive Gateway Modules
Ideal for central gateway ECUs that require multiple CAN FD branches to bridge communication between different vehicle sub-networks.
Body Control Electronics
Used in complex body control modules to manage multiple communication lines for lighting, climate, and comfort functions.
Industrial Automation Control
Suitable for high-density industrial controllers and PLCs that need dual-channel CAN isolation and high-speed data throughput.
Redundant Safety Systems
Supports redundant communication paths in safety-critical systems to ensure uptime in the event of a single-channel failure.

Getting Started

To evaluate this part, design a PCB with appropriate termination (typically 120 ohms) and 0.1uF decoupling capacitors on the VCC supply. Ensure the DFNW14 thermal pad is soldered to a ground plane to manage heat during high-speed dominant states. Utilize the STB pin to toggle between Normal and Standby modes via a microcontroller GPIO.
