Digital Isolators Digital isolators are a type of electrical isolation technology used primarily in industrial applications. They are designed to provide electrical isolation between two points, which can help reduce EMI, reduce power consumption, and improve system reliability. The ISO7321CQDRQ1 is one such isolation device, and its application field and working principle are the focus of this article.The ISO7321CQDRQ1 is an integrated circuit digital isolator used primarily in industrial applications. It operates by providing electrical isolation between two isolated channels while allowing a controlled current flow. The device utilizes capacitive coupling, a method of transferring an electrical signal across two non-directly connected pieces of circuitry. This isolation ensures that electrical signals are kept separate, thus reducing the risk of EMI and interference.The ISO7321CQDRQ1 is used in a variety of industrial applications. These include: motor control, load cell signal conditioning, data-logging, signal acquisition, communication interface and location tracking. The device is designed to reduce the need for bulky shielding, while providing a higher level of isolation than standard digital isolation technologies. The device is also suitable for use in environments where immunity to high magnetic fields is required, due to its scalable isolation design.The ISO7321CQDRQ1 operates via a simple 3-phase switching principle which ensures that the channels are properly isolated and that the necessary signal transmission is achieved. The integrated circuit components require only a single supply voltage to power the device, thus reducing system cost and improving overall system performance.The ISO7321CQDRQ1 features a wide range of channel performance variations. Higher capacitance channels provide better channel signal transmission, while lower capacitance channels allow for higher current flow. This allows for a number of isolation customization options, such as allowing for higher speed and increased resolution of signals passing through the device.The ISO7321CQDRQ1 has several safety features built-in. This includes overcurrent protection, which prevents current from exceeding a set threshold. Another safety feature is overvoltage protection, which ensures that the voltage between the two isolated channels is held within a safe range. Finally, the device has built-in surge protection, which helps to protect against power surges and other unexpected power events.The ISO7321CQDRQ1 is a reliable and versatile digital isolator suitable for use in a variety of industrial applications. Its 3-phase switching principle, wide range of channel performance, and safety features make it an ideal choice for designers looking to improve system performance and reliability. Its ability to provide electrical isolation between two isolated channels while allowing a controlled current flow makes it an ideal solution for applications such as motor control, load cell signal conditioning, and data-logging in industrial environments.
