Digital isolators are used to transfer digital signals across an isolation barrier. These isolators employ RF coupling techniques to transmit digital information across an isolation barrier. It is used as a substitute to optocouplers. Optocoupler is far too slow and error prone for high speed (1MHz+) digital signals. Digital isolator is comparatively faster and less error prone. It has a wide application in gate drivers, DC/DC converters, ADCs, USB & other communication ports, and CAN isolation. They are used in several sectors such as industrial, healthcare, automotive, and telecommunications. The use of digital isolator in industrial sector is expected to dominate the market because the digital isolator proves to be a vital means of receiving efficient and low-cost solutions for equipment safety and data transfer compared to optocouplers. Rise in demand for noise-free electronics and increase in usage of renewable energy sources drive the the digital isolators market growth. Moreover, adoption of digital isolator as a substitute to optocouplers fuels the growth of the market. However, digital isolators’ inability to transmit low-frequency signals without the use of modulators is expected to restrain the growth of the market. Furthermore, high cost of digital isolator may also hinder the growth of the digital isolated market. There are several players in the digital isolators market and product launch, product development, business acquisition, and business expansion are the growth strategies adopted by the key players. For instance, Texas Instruments has launched ISO776x-Q1 High-speed, robust EMC, reinforced six-channel digital isolators with 5000-VRMS (DW package), and 3000-VRMS (DBQ package) isolation ratings per UL 1577. The ISO776x-Q1 family of devices provides high-electromagnetic immunity and low emissions at low-power consumption, while isolating CMOS or LVCMOS digital I/O.
Some of the major factors that are expected to drive the growth of the digital isolator market include increasing in adoption of digital isolators as a substitute for optocouplers, growth in demand for noise-free electronics, and rise in usage of renewable energy sources. However, digital isolators’ inability to transmit low-frequency signals without the use of modulators and their high costs restrain the market growth.
