Digital Isolator Market Drivers
Growing preference of digital isolators over traditionally used optocouplers is driving the growth of the market
The
application of digital isolators over optocouplers have a wide range of
advantage which includes advantage in terms of size, the digital isolators are
faster, use less power consumption, are reliable and easier to integrate into a
module. Traditionally designers had limited options when it came to choosing a
proper isolation barrier system used in modules for healthcare, and industrial
applications. Understanding the nature and interdependence of three key elements
of a digital isolator is important in choosing the right digital isolator.
These elements are insulation material, their structure and data transfer
method. These are key factors driving the application of digital isolators,
thus aiding in Digital Isolator market size growth in terms of revenue. In
2022, according to an article published by Analog Devices, Inc., designers are
switching to incorporating digital isolators to abide by safety regulations or the reduction of noise. The article further confirms the application of digital
isolators offers performance advantage in an industrial motor drive
application.
The integration of a wide range of components, modules and equipment, which function at different levels of voltage is driving the demand for digital isolators.
There
is a growing trend to integrate digital isolators in a wide range of machines to
isolate machines from the electricity to disrupt the current flow direction. This is
done to address the challenge faced by end users and manufacturers while they
look to run their facilities and equipment at low-cost controls, after-market machine components, and reduce machine downtime, among others. Further, they
are combining high-current machines, high-voltage industrial CNC machines and
robots with low-current, low-voltage. This situation is a challenge for the
system integrators and this challenge can be overcome with the integration of digital isolators. Capacitive, inductive and various other techniques are used for
powering different sections of electrical systems. In high-voltage equipment,
digital isolators provide signal isolation and level-shifting to ensure proper
operations of different circuits. They also protect users from electric shocks.
This is driving the market growth in terms of revenue. In 2020, Digi-key announced
the launch of its industrial communication networks which are protected with the integration
of digital isolators. digital isolation, based on chip-scale transformers, has
made possible RS-422/RS-485 transceivers that integrate both isolated DC-DC
regulators and a three-channel signal isolator on a single chip.
Digital isolation barrier devices are key for the efficient functioning of connected factories.
These
devices are used in data acquisition systems, sensors and high-speed
communication infrastructures of connected factories. The explosion of the
industrial Internet of things (IIoT) is predictable to increase demand for the digital isolator market during the forecast period, 2022 to 2027. The IIoT
market is expected to grow at a CAGR of 12.1%, from 2022 to 2027. In 2021,
some of the examples of key players offering digital insulators are Silicon Labs
provides the Si838x PLC input isolator, i834x isolated switch and Si875x SSR
replacement systems ideal for industrial automation equipment.
Digital Isolator Market Challenge
High cost of integrating digital isolators compared to traditionally used optocouplers
Digital isolators are expensive compared to traditionally used optocouplers. Therefore, small companies prefer to use low-cost isolation barrier solutions over digital isolators. Some companies have priced their digital isolators at a lower cost. However, these products have limited utility or application. To achieve channel counts and functional integration, they are fabricated with conventional semiconductor process technology. therefore, the high cost of digital isolation barrier technologies used in digital isolators is posing a key challenge for the market growth. Thus, the high cost of integrating digital isolators is a key challenge faced by the players operating in the digital isolator market. However, designers, also looking for metal-oxide-semiconductor (CMOS) process technology which is used in digital signals isolators is gaining popularity. These techniques will help the designers to create compact, low-cost, reliable and high-performance digital isolated circuits that consume less power than the optocouplers. This is expected to drive the market in the near future. In 2020, according to a report by WTWH Media LLC, the application of an optocoupler saves a great deal of the cost of replacing components and makes it convenient to control the connection between two circuits by connecting/disconnecting an optocoupler. The application of optocouplers over digital isolators can save 30% – 40% of the cost.
