If you want to truly delight customers with your small, battery-powered products, then you probably have long battery life on your list of design requirements. Extending battery life isn’t an easy task, especially since your product’s small form factor will only allow a small battery.
A common factor for many small, smart, and connected devices is that they spend a fair amount of their time in shutdown mode. For example, consider medical patches. These patches could be sitting on storeroom shelves for many months before they’re used by patients. You won’t want the battery to have drained while on the shelf. And once a patient is wearing the patch, the patch will likely spend a lot of time in standby mode, waking now and then to deliver insulin or perform some other action, or transmit data to the cloud. So while such devices are in these passive modes, you need to uncover ways to improve the power savings.
A power supply’s quiescent current (IQ) is the biggest contributor to a system’s standby power consumption. Standby current is becoming more important as sleep and hibernate functions consume extended periods of time. Therefore, lowering quiescent current provides a means to extend battery life.
Electronic Design is hosting a free webinar at 2 p.m. Eastern Daylight Time on Tuesday, May 23. “How to Know When It’s Time to Lower Your IQ” will show you ways to overcome the design challenges of limited space and ultra-low-power operation. You’ll learn about nanoPower ICs with ultra-low quiescent current (<1uA) that can extend battery life and also reduce the PCB size. They’re ideal for internet of things (IoT) applications, wearables, and other small, battery-powered products. Register today for the hour-long session and find out why it’s often smart to have a low IQ.
