Summary

With the increasing adoption of in-package Hall-effect current sensors in solar systems, it is essential to discuss the technical requirements and design considerations for their implementation. This application note addresses several key aspects critical to designing a high-performance and robust in-package Hall-effect current sensor-based current sampling circuit for solar systems. Special attention must be given to thermal capabilities, surge protection, and isolation to prevent sensor failure. Additionally, accuracy, bandwidth and delays are crucial parameters for achieving a high-performance current sampling system.
