Current/voltage/power monitors

Optimize your system with power monitoring and improved accuracy all with a wide common-mode range

parametric-filterView all products
Digital power monitors perform mathematical processing on chip, freeing up system processors to handle other tasks. Providing higher bit-depth with additional features, such as ALERTs, energy accumulation, and ambient temperature sensing, our portfolio of digital power monitors helps address the needs of various application types, especially those that need multidecade current sensing from 1000 A to 100 mA.
