Low Quiescent Current (Iq): Extending Battery Life Without Compromise
October 18 @ 11:00 am - 12:00 pm
Minimizing Iq is a key factor in managing battery life and enabling energy harvesting solutions. An Internet-of-Things (IoT) sensor node is one of the best examples of why it's important to minimize Iq. Because these types of systems spend the majority of their time (>99%) in standby mode, the Iq in standby mode tends to be the limiting factor for battery life and utilizing energy harvesting techniques. Careful optimization of low-Iq power management blocks makes it possible to extend battery life from two years to more than ten years. Recent breakthroughs have been achieved in reducing Iq <60nA for power management building blocks such as DC/DC converters, power switches, low-dropout regulators (LDOs) and supervisors without the classical trade-offs . More importantly, this presentation will highlight some of the pitfalls to avoid and remaining challenges on the journey to achieving lower Iq.
