TCAN1042HVDRQ1 Integrated Circuits (ICs)

Introduction

TCAN1042HVDRQ1 is a two-channel CAN transceiver with a galvanic isolation of up to 1.5 kV. Isolation between the two CAN channels is provided by a large center-tapped transformer, and additional transceiver channels may be provided by additional isolated transformers. It is designed to support the widely used CAN protocol. This transceiver is compliant with the ISO11898-2 and ISO11898-5 standards, and is able to support high speed and low speed data rates. It is a compact, low-cost, and low-voltage device that can be used in a wide range of application fields.

Application fields

Examples of application fields include automotive, industrial automation, building automation and medical systems. This transceiver can be used in many types of applications where the requirement for electrically isolating the CAN data busses is of utmost importance. It can also be used in applications such as industrial control systems, medical equipment, and in-car sensor systems. Additionally, it can be used in remote monitoring and control systems, in CAN-based broadcast networks and in CAN bus systems.

Working Principle

The working principle of the TCAN1042HVDRQ1 is to provide electrical isolation between the CAN-bus and the various user devices connected to it. It is composed of several components, such as transformers, high-speed drivers, receivers, and a wide range of error-detecting and protocol handlers, as well as other circuitry. The principle of operation for each of these individual circuits within the TCAN1042HVDRQ1 is specialized to different solutions, but the main concept is the same for all: electrical isolation of the two separate data busses.

The transformers provide galvanic isolation between the two busses, allowing the two data busses to be linked without any potential risk of shorts. The drivers and receivers provide differential signaling so that data can be transferred with minimal distortion and noise. Additionally, the TCAN1042HVDRQ1 provides error detection and protocol handlers so that the CAN messages can be correctly delivered and acknowledged.

Furthermore, the TCAN1042HVDRQ1 also comes with a wide variety of features designed to make the system more reliable. For example, it also provides thermal protection against overheating, and over- or under-voltage protection. Additionally, it can also provide protection against short-circuits and reverse currents.
