As the core technology in the field of electrical isolation, they not only enhance system safety but also strengthen signal stability and reliability. By enabling signal transmission between circuits without direct electrical connections, they greatly improve system safety, signal stability, and reliability. Working Principle and Classification of Isolation Chips The core function of isolation chips is to achieve electrical isolation, transmitting signals between two circuits without creating an electrical connection. This isolation is achieved through internal isolation components such as optocouplers or transformers. The main technological routes for isolation chips include optical coupling isolation, capacitive coupling isolation (cap coupling), and magnetic coupling isolation (magnetic coupling). ● Optical coupling isolation: Signals are transmitted in the form of electro-optical-electrical, using light signals between the light-emitting device and the photo-sensitive receiver to convey information. ● Capacitive coupling isolation: Utilizes high-frequency signal modulation and demodulation to transmit signals through capacitive isolation, characterized by simplicity and low cost. ● Magnetic coupling isolation: Based on chip-sized transformers, using CMOS process + coil structure, it offers fast transmission speeds and strong reliability. Isolation chips can also be classified according to different functional applications, specifically into digital isolation chips, isolation drive chips, isolation sampling chips, and isolation power management chips. 1. Digital isolation chips: Basic isolation devices used for signal transmission. 2. Isolation drive chips: Integrate gate drive with standard digital isolators to provide electrical and signal isolation. 3. Isolation sampling chips: Include isolated operational amplifiers and isolated ADCs for signal sampling or analog-to-digital conversion. 4. Isolation power management chips: Integrate power isolation circuits and signal isolation circuits to achieve power and signal isolation. History of Isolation Chip Development The development of isolation chips began in the 1960s with the release of the first batch of optoelectronics, which laid the foundation for isolation technology. Optocouplers transmit signals in the form of electro-optical-electrical but suffer from slow transmission speeds, propagation delays, and large deviations. With technological advancements, by the late 1990s, CMOS digital isolation chips were successfully developed, offering a new solution for isolation. Digital isolation chips combine standard CMOS silicon technology, featuring smaller geometries and higher manufacturing process repeatability and stability. Over time, isolation chip technology has undergone significant evolution, from early optocouplers to today's CMOS digital isolation chips. This technological progress has brought significant performance improvements, especially in key timing parameters such as transmission delay, pulse width distortion or deviation, device consistency, and common-mode transient immunity (CMTI). Digital isolation chips, with their low power consumption and multi-channel integration capabilities, are gradually replacing traditional optocoupler applications. Moreover, with the rapid development of application fields such as information communication, industrial control, and new energy vehicles, digital isolation chips are evolving towards faster transmission speeds, higher transmission efficiency, greater integration, stronger pressure resistance, lower power consumption, and higher reliability to meet the growing market demand.
