Current measurements, typically measured between 100 A to 1000 A on the power-drive side, also known as the hot side, are galvanically isolated and sent across to the microcontroller (MCU) side, also known as the cold side.\r\n\r\nHowever, a new active shunt technology offers an all-in-one solution that combines highly accurate measurement and isolation in a single package.\r\n

Current-monitoring applications<\/strong><\/h2>\r\nAny application that generates or uses significant amounts of electrical power needs to operate as efficiently as possible; in many cases, this means there will be some form of automatic closed-loop feedback that requires accurate current sensing.\r\n\r\nLarge battery systems have become more prevalent in recent years, providing power to essential buildings such as data centers and hospitals.\u00a0<\/strong>Monitoring battery capacity and usage requires accurate current measurement.\u00a0Motors\u00a0<\/a>are being used more than ever to automate our world; as we move toward more efficient brushless DC motor types, current measurement is an essential aspect of electronic commutation.\r\n\r\nMany high-growth sectors, including renewable energy, EVs and hybrid EVs (HEVs), also require accurate current monitoring for management, reporting and control.\r\n\r\n
