Overview

The TCAN1042HGDRQ1 is an automotive-qualified (AEC-Q100 Grade 1) CAN transceiver designed to bridge a CAN protocol controller with the physical two-wire bus. This high-speed device supports both classic CAN and CAN FD data rates up to 5 Mbps, featuring enhanced bus fault protection up to plus or minus 70V. It is functional safety-capable and includes integrated features to simplify EMC compliance without external common-mode chokes.

Why Choose This Part

This transceiver offers a wide receiver common-mode input voltage range of plus or minus 30V and high IEC ESD protection up to 15 kV, ensuring robust operation in harsh environments. It features a low-power standby mode with a 22 microamp sleep current and includes a TXD dominant time-out function to prevent bus blocking. Additionally, its level-shifting I/O supports both 3.3V and 5V microcontrollers directly.

Applications

Automotive Body Control Modules
Ideal for vehicle gateways and lighting controllers requiring AEC-Q100 reliability and high ESD protection.
Industrial Automation Systems
Used in factory floor networking where long cable runs and high common-mode noise immunity are essential.
High-Voltage Battery Management
The 70V bus fault protection provides a safety margin in EV battery systems and power electronics.

Getting Started

To evaluate this part, use the TCAN1042DEVM evaluation module which provides a pre-populated SOIC-8 footprint and termination resistors. Connect the TXD and RXD pins to any MCU with a CAN controller, ensuring the VCC supply is between 4.5V and 5.5V for proper operation. Ensure high-speed layout techniques are followed for the CANH and CANL differential pairs to maintain signal integrity at 5 Mbps.
