Silicon Laboratories Inc. introduced a web-based Isolator Power Consumption Calculator that streamlines the process of assessing system power budgets for applications requiring digital isolation. The free online utility enables developers to define basic information about their isolation set-up and then calculate the power consumption in a matter of minutes.
The power consumption calculator is especially helpful for power-sensitive and thermally constrained designs in small enclosures such as industrial process control modules or programmable logic controllers. In these and similar designs, the developer must understand the power consumption of every component in the system including the digital isolator.
The calculator is intuitively easy to use. The user simply selects the settings that match the design such as total number of channels, VDD supply voltage and individual channel parameters, and then clicks “Get Results” to obtain detailed power and current data.
Without access to such a tool, the developer would need to extrapolate power specifications from data sheets or conduct extensive calculations and then guess at some of the isolation parameters.
