Skyworks Solutions is committed to customer enablement and offers a wide variety of evaluation tools and reference designs to allow customers to become familiar with the devices and start designing a solution rapidly. The Si890xPWR-KIT is a reference design/evaluation board that allows customers to quickly evaluate the Si890x devices for AC line monitoring. A user’s guide with detailed information about the circuit is also available. Three application notes are available (at launch). AN635 describes unique features of the Si8900 with its UART interface. AN637 provides the framework for choosing a master controller to pair with the Si890x, and AN638 goes into additional details about using the Si890x for AC line monitoring.
