The Si890x family extends Skyworks Solutions industry leading isolation technology with the addition of an analog-to-digital converter. The integrated device creates an ideal solution for power line, or AC mains line, monitoring. There are many market segments where mains line monitoring is advised. Generally, systems drawing power from the AC mains line that are concerned with efficiency or power quality would be monitoring the mains. Applications that deliver power onto the mains are also concerned with AC mains line monitoring. In such an application, it is often necessary to monitor both the existing mains and the characteristics of the power being injected. A few applications that interact with the AC mains line in this fashion are power converters (especially solar inverters), UPS systems, smart appliances, and electric vehicle charging stations.
