Global Digital Isolator Market: Overview

Digital isolator is one of the crucial components in modern-day electronics. These isolators are metal oxide semiconductors. Digital isolator is used to get a digital signal across a galvanic isolation boundary. The digital isolators act and serve the similar purpose just as optocouplers. But the only difference is that optocouplers are very slow in capturing very high-frequency digital signals, whereas digital isolators are not. Additionally, the technology used in optocouplers in comparison to digital isolators is very different. In the DC-to-DC converters, the digital isolators are used in batteries, solar inverters. and industrial equipment. Several manufacturers across the globe are investing in DC-to-DC converters for proper utilization of digital isolators. Moreover, digital isolators are also used in CAN Bus, mainly for automation in the automotive and industrial sector.

Digital isolator market is experiencing the highest rate of growth in developed as well as developing countries. The growth and development of this market are majorly driven by the capability of digital isolators to detect high-frequency digital signals even at higher altitudes. Big organizations, like Texas Instruments, have started offering low-emission, reinforced and high-efficiency digital isolators. The reinforced digital isolators help in providing support to perform reliable operations in the industrial sector. Many business verticals or sectors, for example, the smart manufacturing organizations while manufacturing smartphones prefer installation of noise-free electronic components. As the smartphone manufacturers seek to make their products and offerings more compact and feature-enriched, the demand for smaller-sized electronic components has been witnessing an increased demand. This leads to the isolation of devices that might produce noise. The market growth of the digital isolators can be attributed to certain trends, like increased use of renewable energy sources, the growth of noise-free electronics, growing demand of substitute optocouplers, and application of digital isolators’ at a higher range or altitudes.

Digital Isolator Market: Growth Drivers

Driver: Demand for noise-free electronic and electrical circuits has increased dramatically.

Ground loops are a typical source of unwanted noise in electrical and electric circuits, and they can cause them to fail. When two connected terminals of a circuit have differing ground potentials, a ground loop is generated. Current flow in the interconnection as a result of this potential difference, resulting in offset errors. Ground loops are interrupted by digital isolators, which ensure that all circuits have the same ground potential. They interrupt the galvanic path between different ground potentials while allowing analog signals to pass through loops.

Restraint: Digital isolators' inability to pass low-frequency signals without modulators

High-frequency signals are typically transmitted via digital isolators. Modulators are required when low-frequency signals must be sent. The use of digital isolators in many applications is limited as a result of this. Low-frequency data cannot get through the isolation layer of capacitive/magnetic digital isolators, hence modulators are used with them when the frequency range is between 0 and 100 Kbps. This could raise the cost of components used in digital isolators, stifling the market's growth.

Opportunity: Automobile electrification.

The worldwide automotive sector is undergoing enormous transformations in order to reduce its environmental effect. The electrification of vehicle powertrains, which ranges from the installation of start/stop switches to the introduction of fully battery-powered electric vehicles, is commonly seen as a means of moving the global automotive industry toward real sustainability. Electric vehicles are the backbone of the low-pollution automobile industry, and they may dramatically reduce vehicle carbon dioxide emissions. Governments from all around the world are taking steps and developing rules to speed up the adoption of electric vehicles.

Challenge: Digital isolators are more expensive than optocouplers.

In terms of propagation delays, data speeds, and noise reduction, digital isolators outperform analogue isolators. Digital isolators, on the other hand, are more expensive than optocouplers. As a result, optocouplers are frequently employed as low-cost isolation solutions for slow digital signal transmission.

Global Digital Isolator Market: Segmentation

The global Digital Isolator market is segregated based on Data Rate, Channel, isolation type, application, and vertical.
