Infineon introduces the first generation of the new ISOFACE™ dual channel digital isolator combination

     Digital isolators, with their optimized system bill of Materials (BOM), smaller PCB footprint, precise timing characteristics and low power consumption, are the first choice for many modern designs. In addition, the digital isolator features higher common mode transient immunity (CMTI), certified insulation life, integrated functionality, and output enable options. To meet the growing demand for robust high-voltage isolation products, Infineon Technologies has introduced the first generation of the ISOFACE™ dual-channel digital isolators, a new device that is pin-compatible with other suppliers' portfolios.

     The newly launched ISOFACE dual-channel digital isolators further expand Infineon's isolation portfolio for a wide range of applications such as servers, communications and industrial SMPS, industrial automation systems, motor control and drives, energy storage systems and solar inverters. Using Infineon's proprietary coreless transformer (CT) isolation technology, this new advanced IC draws on more than 20 years of expertise and technical expertise to help customers reduce system costs, simplify the design process and accelerate time to market. This comprehensive product family offers multiple channel configurations, default fail-safe outputs, variable or fixed input thresholds, and output enable configurations to meet the needs of different applications.

     The ISOFACE dual-channel digital isolator family offers two data channels in a narrow-body DSO-8 package that supports data transfer rates of up to 40 Mbps and ensures signal integrity over a wide operating temperature range and throughout the production range. Infineon's powerful CT technology enables CMTI to exceed 100 kV/μs, ensuring high immunity to system noise. The digital isolator family can withstand isolation voltages of up to 3000 VRMS, allowing the system to operate reliably in noisy environments with predictable data communication capabilities.

     The device's architecture enables a simple, high-power density design with low power consumption and precise timing to improve system efficiency. The user can choose two default output states, high and low. In addition, the device integrates fault filtering, communication modulation, monitoring, undervoltage locking (UVLO) and other functions, enabling robust fail-safe data transmission even in extreme industrial environments with high voltage and noise. The isolation level of this family also meets the most stringent device standards such as UL-1577 and IEC 60747-17 (VDE 0884-17), and system certifications such as IEC 62368-1.
