Abstract

In recent years, there has been a new trend in solar system applications to use in-package Hall-effect current sensors to replace the traditional through-hole sensors, that benefits system performance, power efficiency and reliability. Summary of Solar Application Scenarios Using In-Package Hall-Effect Current Sensors discusses where in-package Hall-effect current sensors can be used, basic requirements of current sensing in solar systems and how current sensors are used accordingly. This application note continues to further discuss design considerations of using in-package Hall-effect current sensors in solar systems, including current ratings and thermal, accuracy, bandwidth, response time and propagation delay, lightning and surge, isolation and reliability.
