Digital isolators are electronic isolators used in a variety of applications that require isolation of circuits and signals from one another. One of the most widely used digital isolator is the ISO7310FCQDQ1. This digital isolator has become the preferred choice for many industries because of its high performance, low power consumption, and reliability. This article will discuss the application field and working principle of the ISO7310FCQDQ1.
Application Field of ISO7310FCQDQ1
The ISO7310FCQDQ1 digital isolator is primarily used in industrial applications where electrical isolation between circuits is necessary. It is often used in industrial communication systems, motor control systems, and data acquisition systems. The digital isolator is also used in medical equipment including patient monitoring, electrocardiogram (ECG) machines, and ventilators. It is also used in measurement and control systems, such as those used in aerospace and automotive applications where it provides signal transfer without causing interference or noise.
Working Principle of ISO7310FCQDQ1
The ISO7310FCQDQ1 digital isolator operates on the principle of galvanic isolation. Galvanic isolation is a method of electrically separating two or more circuits in order to prevent the transfer of electric current between them. By introducing a non- conducting barrier such as an insulated barrier, it is possible to maintain an electrical connection between the input and output circuits without allowing any current to flow. The ISO7310FCQDQ1 utilizes a two-stage power supply system which allows for higher precision in signal transfer with greater stability.
The ISO7310FCQDQ1 digital isolator is equipped with two galvanically isolated power supplies, a primary AC power supply and a secondary DC power supply. The primary AC power supply is responsible for powering the entire system. The secondary DC power supply is responsible for providing a stable output voltage for the digital isolator. The circuit design uses a transformer with multiple windings to transfer the input voltage from the primary AC power supply to the secondary DC power supply.
The transformer reduces the voltage from the primary AC power supply, while simultaneously converting it into a higher voltage which is used to power the digital isolator. The voltage is then converted by a rectifier circuit and used to power the digital isolator circuit. The digital isolator is then used to transmit the input signal from the primary AC power supply to the secondary DC power supply without any interference or noise, ensuring a reliable and accurate signal transfer.
The ISO7310FCQDQ1 digital isolator is a high performance, low power consumption, and reliable solution for applications where electrical isolation is required between two circuits. Its two-stage power supply system and transformer based transformer for high precision signal transfer ensures reliable and accurate signal transfer without any interference or noise. As such, the ISO7310FCQDQ1 has become the preferred choice for many industries.
