Infineon launches two, four channel digital isolators ...

The ISOFACE devices are based on Infineon’s patented coreless transformer (CT) isolation technology with multiple channel configurations, fail-safe default output states, variable or fixed input thresholds and output enable configurations.

Digital isolators allow 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.

The 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 V RMS isolation voltage, resulting in reliable system in noisy environments with predictable data communication.

The first generation dual-channel 2DIBx4xxF supports data rates of up to 40 Mbit/s, ensuring signal integrity over a wide operating temperature range and across the production spread.

The digital isolators are aimed at server, telecom and industrial SMPS, industrial automation systems, motor control and drives, energy storage systems, and solar inverters.

The devices’ structure enables higher system efficiency in simplified, high-power-density designs with low power consumption and accurate timing performance.

High and low default output state options are available along with glitch filtering, communication modulation, watchdog, and undervoltage lockout (UVLO) to ensure robust and fail-safe data transmission even in a critical industrial environments with high voltages and noise.

The digital isolators also provide isolation according to the most stringent standards, such as UL-1577 and IEC 60747-17 (VDE 0884-17) at the component level, and system certifications, such as IEC 62368-1.

The ISOFACE 2DIBx4xxF is available in a narrow-body DSO-8 package and can be ordered now. In the fall of 2023, the portfolio will be expanded with 4-channel digital isolators qualified for industrial and automotive applications.
