Digital isolation devices are in demand to satisfy the safety regulations even though maximizing the benefits of modern CMOS technology. Digital isolators are typically used between analog-to-digital converters (ADCs) and a microcontroller (MCU) in the signal path, and these applications are boosting the Digital Isolator Market. They are commonly found in the isolated power-supply functions of a given system. Reduced power consumption and transformation in field transmitter are the primary advancements of the digital isolator technology, which are influencing the manufacturers to adopt more number of digital isolators. All these factors are collectively growing digital isolator market demand. Digital isolation components offer multichannel isolation solutions, surges system reliability because of a lower failure rate, and also provide double electrical noise immunity to operate over a broader range of temperature. Thus, the global digital isolator market size stood at $1.5 billion in 2018 and is projected to grow with a CAGR of 6.8% all through the forecast period 2019-2025.
Digital isolator uses a single-ended CMOS technology and acts as the best alternative for an optocoupler, as it reduces the complexity associated with the design and components in the passage of digital signal. Additionally, it does not get damaged over the lifetime of the vehicle, and it also serves even in the harsh operating conditions through the changing seasons. Availability of digital isolators with different isolation ratings coupled with the signal integrity, latency, and EMC considerations are driving the growth of the global digital isolator market. Notably, digital isolator application is raising at a faster CAGR of 8.4% in both telecommunication and automotive industries collectively during the forecast period 2019-2025. These days, numerous hybrid electric vehicles are using iCoupler digital isolators not only to monitor battery levels but also to drive the efficient electric motor. Prevalence of electric vehicles (EVs) and various forms of hybrid electric vehicles (HEVs) on the road is augmenting the global digital isolator market revenue.
Currently, these vehicles comprise a high-voltage battery ranging from 200V to 400V. Higher voltages are intended to enable higher power for maximizing the distance per charge in the future. As a consequence, this high-voltage battery demands the use of isolators mainly for signal transfer and safety across various voltage domains inside the vehicle. Practically, almost all foremost automobile makers have a future EV rollout plan. The high-temperature operation, noise immunity, and stability enabled by the digital isolator technology are highly accepted in the automotive industry with is to say that the automotive industry is an early adopter of digital technology, it is playing a vital role in the digital isolator market. Especially, battery management systems and chargers are the critical end applications which are driving the necessity for isolators in the EV market.
Raise in the incorporation of CMOS isolators at isolated power supplies, which are used in telecom base stations and servers. It is helpful to power the infrastructure to cope up with the increasingly connected world via the Internet of Things. Isolated power supply manufacturers are the quick adopters of digital. Furthermore, these power supplies are utilized mainly for servers and telecom base stations. CMOS-based digital isolators use the ultramodern semiconductor technology to its full extent and provide multifarious advantages to the system designer. These advantages have been shaping the evolution of power supplies, green energy, and automotive industries.
Digital Isolator Market in APAC Region:
Digital isolators play a prominent role in circuit design and assist the developers to create an effective design. Increase in the number of electronic integrated circuits imports in APAC has been expanding the scope for digital isolator market players in this region.
