The operation of a high side switch becomes smoother, smarter, and enhanced when adding features such as diagnostics and fault reporting. Diagnostics and fault reporting are key features in high side switches to protect power supplies and loads such as LEDs or motors safe while keeping the switch intact. The following application report goes over the diagnostics and fault reporting that are provided in TI’s Smart High Side Switch solutions in both normal and fault conditions such as accurate current sensing, short-to-GND detection, and open load detection. Using this document, designers can take advantage of each advanced function and make the most of TI’s high side switch in their application.
