For instance, in June 2023, Infineon Technologies AG (Germany) launched the first generation of its ISOFACE dual-channel digital isolators designed for robust high-voltage isolation. These new isolators are pin-to-pin compatible with offerings from other suppliers. It provides modern designs with an optimized system Bill of Material (BOM), reduced Printed Circuit Board (PCB) area, accurate timing characteristics with lower power consumption, certified insulation life, improved Common-Mode Transient Immunity (CMTI), etc.

The increased need for healthcare applications drives considerable growth in the digital isolator industry. As healthcare technologies advance, the demand for safe and dependable data transfer between medical equipment increases. Digital isolators promote electrical safety by reducing potential risks and improving data integrity. The growing use of telemedicine, remote patient monitoring, and other healthcare applications fuels demand for digital isolators, propelling the market forward.

Data rate constraints are a barrier in the digital isolator industry as certain applications, particularly those seeking high-speed communication, may find the confined data transfer rates prohibitive. While digital isolators provide benefits in terms of safety and signal integrity, their inability to match the data rates of some analog isolators limits their suitability for applications requiring rapid data transmission, potentially stifling their adoption in certain high-frequency and data-intensive scenarios.
