Infineon’s new digital isolators offer robust high-voltage Isolation, best-in-class efficiency and noise immunity

Jun 19, 2023 /SemiMedia/ — Infineon Applied sciences AG has launched the primary era of ISOFACE™ dual-channel digital isolators to fulfill the rising demand for sturdy high-voltage isolation. The brand new gadgets are pin-to-pin appropriate with different suppliers’ portfolios.

The brand new ISOFACE dual-channel digital isolators are the most recent addition to Infineon’s portfolio of isolation merchandise for a variety of functions. These embody server, telecom and industrial SMPS, industrial automation techniques, motor management and drives, power storage techniques, and photo voltaic inverters. Primarily based on Infineon’s patented coreless transformer (CT) isolation expertise, the brand new state-of-the-art ICs leverage greater than 20 years of experience to ship system price financial savings, streamlined design processes and accelerated time to market. The excellent product vary gives a number of channel configurations, fail-safe default output states, variable or fastened enter thresholds, and output allow configurations to fulfill numerous utility necessities.

The ISOFACE dual-channel digital isolator household gives two information channels in a narrow-body DSO-8 package deal, supporting information charges of as much as 40 Mbps and guaranteeing sign integrity over a large working temperature vary and throughout the manufacturing unfold. Infineon’s sturdy CT expertise ensures excessive immunity to system noise with a CMTI of greater than 100 kV/μs. The digital isolator household withstands as much as 3000 V RMS isolation voltage, leading to dependable system operation in noisy environments with predictable information communication.

The gadgets’ construction allows larger system effectivity in simplified, high-power-density designs with low energy consumption and correct timing efficiency. Each excessive and low default output state choices can be found. As well as, options reminiscent of glitch filtering, communication modulation, watchdog, and undervoltage lockout (UVLO) are built-in to make sure sturdy and fail-safe information transmission even in a essential industrial environments with excessive voltages and noise. In addition they present isolation in keeping with probably the most stringent requirements, reminiscent of UL-1577 and IEC 60747-17 (VDE 0884-17) on the element degree, and system certifications, reminiscent of IEC 62368-1.

ISOFACE dual-channel (2DIBx4xxF) digital isolators can be found in a DSO-8 package deal and will be ordered now. Within the fall of 2023, the portfolio might be expanded with 4-channel digital isolators certified for industrial and automotive functions.
