Digital Isolator Market: Overview

The market size for digital isolators was USD 1,729.4 million in 2021, and it is projected to grow at a CAGR of 8.6 percent during the forecast period. The digital isolators market is expected to grow due to an increasing trend of replacing conventional optocouplers with digital isolators and the growing popularity of noise-free devices and electronics. Further, the market growth is expected to be driven by the increasing use of digital isolators in industrial applications, including field uses, motor controls, and power supplies. Furthermore, stringent battery safety requirements for automobiles and renewable energy sources are driving the demand for digital isolators over the next few years.

Digitized signals are transported through a digital isolator that works only with digital signals to cross galvanic isolation boundaries. With a digital isolator, you can improve data rates, integrate multiple isolation channels, reduce costs, decrease external components, and increase dependability. This enhanced digital isolator helps ensure the reliability of industrial systems by providing excellent efficiency and minimal emissions. Many companies, including Texas Instruments, offer this enhanced digital isolator. It reduces board space and simplifies system design costs by integrating separate power and data up to 100 Mbps. Several trends are driving the digital isolator market, including increased demand for noise-free electronics, use of renewable energy sources, replacement of optocouplers, and higher altitude applications of digital isolators. When an electronic device or a semiconductor integrated circuit isolates a system from unwanted ac, dc, and signal currents, they enable power transfer and signal transmission.

Further, the availability of digital isolators as an alternative to optocouplers fuels market growth. However, the inability of digital isolators to transmit low-frequency signals without external modulators is expected to restrain the market growth. Furthermore, the high costs of digital isolators may also hinder the growth of digital isolators. It is important to note that several players are involved in the digital isolators market, and their growth strategies include product launches, product development, acquisitions, and expansions. As an example, Texas Instruments has introduced ISO776x-Q1 High Speed, Robust EMC, and 6-channel digital isolators with 5000 VRMS and 3000-VRMS isolation ratings according to UL 1577. CMOS or LVCMOS digital I/O can be isolated with ISO776x-Q1 devices, which provide high electromagnetic immunity and low electromagnetic emissions at low power consumption.

Digital Isolator Market: COVID-19 Impact

A major downfall affected the global economy due to the COVID-19 pandemic. Businesses of all sizes were affected, irrespective of their size. Also, governments around the world imposed lockdowns on their nations to prevent the pandemic's spread, resulting in temporary industrial shutdowns. People across the globe faced a shortage of various goods and services due to the industrial closure. Further, due to government-imposed travel restrictions, the worldwide supply chain was also severely disrupted, resulting in significant losses for various industries.

Digital Isolator Market: Drivers

Safety Requirements for Batteries in Automobiles to Drive Market Growth

The automotive industry has announced plans to introduce battery electric cars (BEVs), plug-in hybrid electric cars (PHEVs), and full hybrid electric cars (FHEVs). BEVs offer quiet, emission-free transport. The new electronic drivetrain and battery systems require high-wattage power electronics as automotive design moves toward electrification. In designing solutions for automotive xEV applications, designers may have to overcome the challenge of communicating digital data between high voltage and low voltage battery domain electronics. Battery current measurements, battery cell voltage monitoring, motor control, and high voltage contactor monitoring face this challenge. A semiconductor-based galvanic isolation system is required to connect a low-voltage digital controller to a high-voltage electronic system in a modern electric vehicle. With digital isolators, the designer can significantly save on both current consumption and PCB space.

Increasing Number of Safety Standards for Industrial Automation Driving Market Growth

Incorporating electronic controls into multiple industrial systems over networks offers several benefits and challenges to machine operators. Automated machine safety offers great protection to machine operators. Manufacturers and end users are changing their approaches in the current era of machine safety standards. They prefer a low-cost control system, readily available machine components, decreased machine downtime, etc. The challenge for system integrators is to combine high-voltage, high-current machines with low-voltage, low-current data acquisition systems and networked communication systems. Digital isolators with machines resolve this challenge since they isolate different functional sections of electrical systems so that current does not flow directly between them. Different electrical systems are powered by capacitive, inductive, and a variety of other techniques. The purpose of digital isolators in high-voltage equipment is to isolate signals and shift levels so that different circuits run properly. They also protect the users from electric shock. The Si838x PLC input isolator is one of Silicon Labs' products, and the Si834x isolated switch is another. Silicon Labs is a leading manufacturer of digital isolators for industrial automation. One of its SSR replacement systems is the Si875x. Silicon Labs produces digital isolators that are ideal for industrial automation.

Digital Isolator Market: Restraints

High Costs Compared to Optocouplers to Hamper Market Growth

Compared to conventional optocouplers, digital isolators perform better regarding propagation delays, data rate, and noise reduction. However, digital isolators are more expensive. Optocouplers are commonly used as low-cost isolation solutions when digital signals are transmitted slowly. Digital isolators are offered at low costs by several companies, but they are not useful for PV inverters since they are fabricated with conventional semiconductor processing technologies in order to achieve channel counts and functional integration. Digital isolators that use complementary metal-oxide-semiconductor (CMOS) process technology are gaining popularity among designers due to the high cost of alternative isolation technologies. It enables designers to design low-cost, compact, reliable, and high-performance isolated circuits that use less power than optocouplers. In addition to their type and ability to pass current, digital isolators are priced according to the application for which they will be used.

Digital Isolator Market: Segment Overview
