Product Introduction

Overview

The TCAN1046DMTRQ1 is a high-speed CAN (Controller Area Network) transceiver produced by Texas Instruments, designed specifically for automotive applications. This model is part of the TCAN1046-Q1 family, which supports both traditional CAN and CAN FD (Flexible Data-Rate) networks, enabling data rates up to 8 Mbps. The TCAN1046DMTRQ1 is housed in a VSON-14 package, making it suitable for compact and high-reliability automotive systems. Its primary market positioning is in automotive electronics, targeting applications such as body control modules, gateways, and advanced driver-assistance systems (ADAS). The device stands out for its dual-channel capability, independent power supply for each channel, and robust fault protection features, making it a competitive choice for automotive communication networks.
