3 Summary

With the continued investment and development of solar energy and ESS, more accurate and reliable current sensing technologies can make the grid safer and more efficient on energy harvest. In-package hall-based technologies such as TMCS112x and TMCS113x from Texas Instruments, can not only provide high accuracy combined with low drift, enabling accurate current measurements over both lifetime and temperature, but also have ease of use and low cost, which makes this popular to replace the traditional thorough-hole hall-effect current sensors. This application note summarizes common solar application scenarios where in-package hall-effect current sensors can be used. Read the following Design Considerations of In-package Hall-effect Current Sensor in Solar System, application note to learn more design challenges and how to solve those challenges.
