11/10/2023 0 Comments Infineon digital isolator![]() 2 -channel digital isolators and gives design guidance for system engineers designing galvanical isolation in high-voltage (HV) applications. Infineon also announced that later this year, it will add four-channel digital isolators qualified for industrial and automotive applications. This document introduces Infineon’ ISOFACE. ![]() The ISOFACE dual-channel digital isolators are available in a DSO-8 package and can be ordered now. Isolation is according to 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. Features such as glitch filtering, communication modulation, watchdog and undervoltage lockout (UVLO) ensure robust and failsafe data transmission even in a critical industrial environments with high voltages and noise. Both high and low default output state options are available. The devices’ structure enables higher system efficiency in simplified, high power density designs with low power consumption and accurate timing performance, continued the company. The digital isolator family withstands up to 3000V RMS isolation voltage, for reliable system operation in noisy environments with predictable data communication. Digital Isolators High-Immunity, 5.7kVRMS Reinforced Dual-Channel 2/0 Digital Isolator. With a wide supply voltage range, TTL input thresholds and default output state low, it is the perfect fit for high-side floating drive applications with feedback. Hot ISO7820DWW electronic component of Texas Instruments, ISO7820DWW. CT technology guarantees high immunity to system noise with a CMTI of more than 100kV per microsecond, reported Infineon. Infineon’s ISOFACE dual-channel digital isolator 2DIB1410F (with 1 forward channel and 1 reverse channel) provides robust isolation for high voltage applications. The ISOFACE dual-channel digital isolator family provides two data channels in a narrow-body DSO-8 package, supporting data rates of up to 40Mbits per second and ensuring signal integrity over the operating temperature range and across the production spread. Based on Infineon’s patented coreless transformer (CT) isolation technology, the ICs offer multiple channel configurations, fail-safe default output states, variable or fixed input thresholds, and output enable configurations to meet application requirements. The ISOFACE 2DIBx4xxF dual-channel digital isolators have been added to Infineon’s portfolio of isolation products for servers, telecomms and industrial SMPS, industrial automation systems, motor control and drives, energy storage systems and solar inverters. ![]() The devices are pin-to-pin compatible with other suppliers’ portfolios. They also offer improved common-mode transient immunity (CMTI), certified insulation life, integrated features and output enable options, said Infineon Technologies as it launched its first generation of ISOFACE dual-channel digital isolators to meet the growing demand for robust high-voltage isolation. The ISOFACE dual-channel digital isolator family supports data rates up to 40 Mbps and ensures signal integrity over a wide ambient operating temperature range. Furthermore, they are certified according to a wide range of system isolation standards, which eases our customer’s system certification process and accelerates their time to market.Digital isolators include an optimised system bill of materials (BoM) and reduced PCB area as well as accurate timing characteristics with lower power consumption. ISOFACE™ digital isolators are certified according to the most stringent component isolation standard for capacitive and magnetic isolators, such as VDE0884-17, UL1577, IEC 60747-17. Infineon ISOFACE ™ digital isolators reduce system standby power consumption and improve system efficiency. The Infineon ISOFACE ™ digital isolators offer accurate timing performance, high propagation delay accuracy, and better channel-to-channel matching, which eases the system design and increases efficiency in SMPS applications. The products are pin-to-pin compatible and can therefore be used as a direct replacement in existing customer designs for supply security. This is due to benchmark's highest CMTI, both TTL and CMOS input threshold options (for dual-channel digital isolators) as well as active-high and active-low output enable (for quad-channel digital isolators), integrated glitch filter, and wide supply voltage range. Infineon ISOFACE ™ digital isolators provide the highest level of robustness, even in noisy environments.
