The 4DIR1400HXUMA1 from Infineon Technologies is a Quad-Channel Digital Isolator IC that is ideal for server, telecom, and industrial switch-mode power supplies (SMPS), industrial automation systems, motor drives, medical equipment, and isolated serial peripheral interface (SPI) applications. It requires an input voltage of 2.7 - 6.5 V. This power management IC (PMIC) supports data rates up to 40 Mbps and ensures robust data communication over a wide ambient operating temperature range of -40°C to +125°C and across production spread. It features coreless transformer (CT) technology that provides high immunity against system noise and withstands up to 5700 V (RMS) isolation voltage. This PMIC includes four data channels, enabling simplified designs with high power density, improved system efficiency, and low power consumption.

This digital isolator IC provides different fail-safe default output options with under-voltage lockout (UVLO) protection to maintain a stable output and prevent false triggers, thereby offering high performance and reliability in a single 300-mil package. It is also provided with variable CMOS input thresholds to support various input requirements of applications. This RoHS-compliant PMIC is available in a surface-mount package that measures 10.3 x 7.5 x 2.65 mm.
