Market Dynamics:
Driver: High demand for digital isolators from electric vehicle and battery pack manufacturers
Automobile original equipment manufacturers (OEMs) worldwide are setting ambitious targets to launch new models of battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and full-hybrid electric vehicles (FHEVs). The BEV mode of transportation is known for its smooth, silent, and eco-friendly ride. As the automobile industry is moving toward electric vehicles, high-wattage power electronics are becoming essential components in the new electronic drivetrain and battery systems. However, EV batteries are susceptible to voltage transients and electrical noise, which can potentially damage sensitive electronics. Digital isolators act as a barrier, protecting critical components from these transients. By providing a barrier between high-voltage and low-voltage sections, digital isolators safeguard the integrity of control signals and data transmission, contributing to the longevity and reliability of the EV battery system. Digital isolators also prevent ground loops, reduce the risk of electrical faults, and enhance the overall safety of the EV battery system. In the event of a fault, digital isolators help contain the impact, preventing the spread of electrical issues. The use of digital isolators enhances the overall reliability of the EV battery system by reducing the risk of electrical faults and ensuring robust communication between components. This increased reliability contributes to the efficiency of the battery system, allowing for optimal performance and longevity. Further, digital isolators facilitate seamless integration with control systems, enabling precise monitoring and control of various parameters within the EV battery. This integration is essential for implementing advanced battery management strategies, optimizing charging and discharging cycles, and ensuring the overall health of the battery pack.
Restraint: Inability of digital isolators to transmit low-frequency signals without modulators
High-frequency signals can be transmitted directly by capacitive/magnetic digital isolators. However, when dealing with low-frequency signals, between 0 and 100 Kbps, signal isolators witness signal integrity and distortion issues, resulting in diminished performance. The absence of modulators exacerbates this issue, as modulation techniques are often employed to enhance the transmission of low-frequency signals in various communication systems. Digital isolators lack the built-in modulation mechanisms necessary to efficiently handle these specific frequency ranges. Hence, there is a need to integrate external modulators or explore specialized isolator designs tailored for low-frequency applications. Thus, the inability of digital isolators to transmit low-frequency signals limits its use in various applications such as process control, sensor interfacing, and audio applications may increase the costs of components used in them, thereby hampering the growth of the digital isolator market.
Opportunity: Increasing use of isolators in harsh environmental applications
The digital isolator market is expected to experience growth due to the increasing demand for robust isolators in harsh environmental applications, including electric motors. These applications face data disruptions from high-voltage transients and electrical stress, therefore there is a need for digital isolators that can withstand these effects. In the past, optocouplers were used in harsh environments as they could handle high voltages with thick layers of internal insulation. However, optocouplers used light-emitting diodes (LED) that lose their light intensity over time and can have reliability issues due to variations in light intensity with temperature. Digital isolators overcome these issues by using semiconductor IC-based dependable circuits to transmit and receive digital signals across isolation barriers.
The insulation of these isolators has also been improved to compete with optocouplers. Digital isolators have immunity against high-voltage transients and noise. Optocouplers can operate in applications with a maximum temperature of 85°C, while digital isolators can perform in high temperatures, that is, more than 125ºC.
Challenges: High cost of digital isolators than optocouplers
Digital isolators are known to offer better performance when it comes to propagation delays, noise reduction, and data rates compared to optocouplers. However, the cost of digital isolators is higher than that of optocouplers. This is why optocouplers are widely used as a low-cost isolation solution to transmit slow digital signals.
While several companies offer low-cost digital isolators, their usage is limited in applications such as PV inverters. These isolators are manufactured using conventional semiconductor process technology to achieve channel counts and functional integration to offset the high prices of alternative isolation technologies used in digital isolators. For instance, digital isolators made using complementary metal-oxide-semiconductor (CMOS) process technology are increasingly adopted by designers. This technology enables designers to develop low-cost, compact, high-performance, and reliable isolated circuits with lower power consumption than optocouplers.
The costs of digital isolators depend on the type of isolators and their capacity to pass current and depend on the applications for which they are deployed. Digital isolators with higher data rates and more channels have higher costs than those with lower data rates and a lesser number of channels. Although manufacturers are developing low-cost digital isolators, the average cost of these devices is still higher than that of optocouplers. Very few low-cost digital isolators are available in the market.
