Overview
The NCV7446MW0R2G, produced by onsemi, is a dual CAN FD (Controller Area Network Flexible Data Rate) physical layer transceiver. This component is designed to interface with two independent CAN physical buses and two independent CAN protocol controllers. It is essentially two fully independent NCV7344 transceivers integrated into one package, ensuring robust communication at data rates up to 5 Mbps, which is essential for CAN FD requirements. The NCV7446MW0R2G is optimized for low electromagnetic emission (EME) and high electromagnetic immunity, making it suitable for various high-speed CAN (HS-CAN) networks, particularly in automotive and industrial applications.
