Product Introduction

Overview

The ISO1042DWVEVM is an evaluation module designed by Texas Instruments to facilitate the evaluation and development of the ISO1042 isolated CAN (Controller Area Network) transceiver. This module supports the ISO1042 device in an 8-pin wide-body SOIC package (package code DWV) and is intended for evaluating the performance of isolated CAN systems. The ISO1042 device itself is a galvanically-isolated CAN transceiver that complies with the ISO11898-2 (2016) standard, offering robust protection and high-speed data transfer capabilities.

Q & A

  1. What is the ISO1042DWVEVM used for?

    The ISO1042DWVEVM is an evaluation module used to evaluate the performance of the ISO1042 isolated CAN transceiver in an 8-pin SOIC package.

  2. What are the key specifications of the ISO1042 device?

    The ISO1042 device supports up to 5 Mbps in CAN FD mode, has ±70 V DC bus fault protection, and operates within a common-mode voltage range of ±30 V. It also has an isolation voltage of 5000 VRMS and supports various logic interfaces.

  3. What are the safety certifications of the ISO1042 device?

    The ISO1042 device has certifications such as 7071-V PKV IOTM and 1500-V PKV IORM, IEC 60950-1, IEC 60601-1, and EN 61010-1.

  4. What is the operating temperature range of the ISO1042 device?

    The operating temperature range is -40°C to 125°C.

  5. What is the purpose of the isolation barrier in the ISO1042 device?

    The isolation barrier, made of silicon dioxide (SiO2), provides 5000 VRMS isolation and prevents noise currents from the bus from entering the local ground, thus protecting sensitive circuitry.

  6. Can the ISO1042 device support different logic interfaces?

    Yes, it supports 1.8-V, 2.5-V, 3.3-V, and 5.0-V logic interfaces to the CAN controller.

  7. What is the significance of the EVM's pre-configured termination network?

    The EVM is pre-configured with a split termination network, common-mode capacitance, and additional caps on the bus for protection, allowing for easy evaluation and setup.

  8. What are some of the protection features of the ISO1042 device?

    The device features DC bus fault protection, undervoltage protection on VCC1 and VCC2, and high ESD tolerance on bus pins.

  9. Is the ISO1042 device suitable for automotive applications?

    Yes, it is suitable for automotive applications and is available in an automotive-qualified version (ISO1042-Q1).

  10. What is the typical use case for the ISO1042DWVEVM in development?

    The ISO1042DWVEVM is used to evaluate the ISO1042 device with minimal external components, featuring test points and jumper options for various configurations.
