The 2DIB0400FXUMA1 from Infineon Technologies is a Dual-Channel Digital Isolator IC that is ideal for solar inverters, industrial automation systems, motor drives, medical equipment, server, telecom, and industrial switch mode power supply (SMPS) applications. It requires an input voltage of 2.7 - 6.5 V. This power management IC (PMIC) consists of logic circuits, a transmit module, a receive module, isolation transformers, voltage regulators, comparators, and protection circuits. It has been designed to deliver a data rate of up to 40 Mbps and ensure robust data communication over a wide ambient operating temperature range from -40°C to +125°C. This PMIC integrates Infineon’s robust coreless transformer (CT) technology that offers high immunity against system noise while providing a withstanding voltage capability of up to 3000 V (RMS). It includes two separate 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 150-mil package. It is also provided with variable input thresholds to support various input requirements of applications. This RoHS-compliant PMIC is available in a surface-mount package that measures 6 x 5 x 1.75 mm.
