New ISOFACE™ portfolio of digital isolators offers robust high-voltage isolation, best-in-class efficiency and noise immunity

Digital isolators have become the preferred choice in many modern designs because of the many benefits they offer. These include an optimized system bill of materials (BOM) and reduced printed circuit board (PCB) area, as well as accurate timing characteristics with lower power consumption. They also offer improved common-mode transient immunity (CMTI), certified insulation life, integrated features and output enable options. Infineon Technologies introduces its first generation of ISOFACE™ dual-channel digital isolators to meet the growing demand for robust high-voltage isolation. The new devices are pin-to-pin compatible with other suppliers’ portfolios.

The ISOFACE dual-channel digital isolator family provides two data channels in a narrow-body DSO-8 package, supporting data rates of up to 40 Mbps and ensuring signal integrity over a wide operating temperature range and across the production spread. Infineon’s robust CT technology guarantees high immunity to system noise with a CMTI of more than 100 kV/μs. The digital isolator family withstands up to 3000 Vrms isolation voltage, resulting in reliable system operation in noisy environments with predictable data communication (more info).
