A major focus in electronic design today is low power consumption. Low quiescent (IQ or IQ ) current plays a major part in designing battery power supplies. More and more electronic end products incorporate batteries to enable them in remote locations.
Some examples of battery-powered devices include wireless security cameras, video doorbells, and smart locks. Utility smart meters; fitness trackers, smart watches, and other wearables for health monitoring; and smartphones get their power from batteries. Many sensors and other devices in factories and other industrial facilities use batteries. Battery life an issue in all of these.
