Infineon extends its ISOFACE™ product portfolio with quad-channel digital isolators for industrial and automotive applications

Modern electronic systems in automotive and industrial applications require robust, efficient, and precise data communication capabilities to ensure optimal performance. To meet these needs, Infineon Technologies is introducing its ISOFACE™ quad-channel digital isolators, emphasizing a broader portfolio of isolation technologies.

The ISOFACE quad-channel digital isolators are available in two categories. The ISOFACE 4DIRx4xxHA family with AEC-Q100 qualification is designed for automotive applications such as onboard chargers (OBC), battery management systems (BMS), inverters, and motor control. The ISOFACE 4DIRx4xxH family is fully qualified according to JEDEC and is designed for industrial applications such as renewables, servers, telecom, industrial switch-mode power supplies (SMPS), industrial automation, and isolated serial peripheral interface (SPI). The products come in a wide-body 300 mil PG-DSO-16 package with four data channels, providing enhanced isolation and ensuring reliable data communications in demanding environments.

The ISOFACE quad-channel digital isolators offer an operating supply voltage range from 2.7 to 6.5 V. Even with this wide supply voltage range, their low current consumption remains efficient, capping at 1.6 mA per channel when operating at speeds up to 1 Mbps with a 3.3 V supply voltage and a 15 pF load capacitance. In addition, Infineon’s robust Coreless Transformer (CT) technology provides high immunity against system noise (common mode transient immunity of minimum 100 kV/µs) and withstands up to 5700 V rms isolation voltage (more info).
