The Automotive Digital Isolators Market size was valued at USD 1.5 Billion in 2022 and is projected to reach USD 2.8 Billion by 2030, growing at a CAGR of 8.6% from 2024 to 2030.
The Automotive Digital Isolators Market is experiencing a significant rise due to the increasing demand for reliable electronic systems in vehicles. These isolators play a crucial role in ensuring the safe and efficient operation of various automotive applications by providing electrical isolation between different components. Among the various applications of automotive digital isolators, three key subsegments stand out: Battery Voltage Monitoring, Battery Current Measurement, and Others. Each of these subsegments plays a pivotal role in enhancing vehicle safety, performance, and energy efficiency.
Battery voltage monitoring is a critical application for automotive digital isolators. In modern electric and hybrid vehicles, the battery is a central component that powers the vehicle. Accurate voltage monitoring is essential to ensure the battery's health and prevent overcharging or discharging, which could damage the battery or affect the vehicle's performance. Automotive digital isolators are used in the voltage monitoring circuits to provide electrical isolation between high-voltage components (such as the battery and powertrain) and low-voltage control circuits (such as microcontrollers and sensors). This isolation ensures that any faults or voltage spikes in the high-voltage system do not harm the sensitive low-voltage electronics. As the demand for electric vehicles (EVs) and hybrid electric vehicles (HEVs) rises, the need for efficient and reliable voltage monitoring systems will continue to grow, driving the demand for automotive digital isolators in this segment.
Battery current measurement is another key application of automotive digital isolators. In electric and hybrid vehicles, accurate current measurement is necessary for tracking the battery's charge and discharge cycles, which helps in optimizing energy consumption and battery longevity. Digital isolators are used to provide safe and accurate measurement by isolating the high-voltage power circuits from the low-voltage measurement circuitry. This ensures that no electrical noise or faults from the high-voltage side affects the low-voltage side, which is critical for precise current sensing. Additionally, this isolation helps protect the control systems from potential faults in the battery management system (BMS). The rising adoption of EVs, coupled with the need for advanced battery management systems (BMS), is expected to fuel the growth of digital isolators in battery current measurement applications, further improving battery efficiency and reliability.
The "Others" segment of the automotive digital isolators market encompasses a wide range of applications, including motor control, safety systems, infotainment, and communication systems. Digital isolators are used in motor control systems to ensure safe operation by isolating the drive circuitry from control signals. In safety-critical systems, such as airbags, ABS (Anti-lock Braking System), and other safety mechanisms, digital isolators provide fault tolerance and electrical isolation to prevent failures that could compromise the vehicle's safety. Moreover, automotive infotainment systems use digital isolators to protect sensitive control electronics from electrical interference. As automotive electronics become more advanced and integrated, the demand for digital isolators in various other applications is expected to grow, further driving the market forward.
