AEM00300-QFN

Overview

The AEM00300-QFN is a highly versatile buck-boost ambient energy manager designed to extract power from high-impedance sources. It features an ultra-low power start-up at 140mV and maintains an industry-leading quiescent current of 5.9nA, making it ideal for self-powered IoT nodes. The device includes integrated battery protection and a dual-cell super-capacitor balancing circuit to manage storage components efficiently.

Why Choose This Part

The AEM00300 excels in ultra-low power environments with a sub-10nA quiescent current that preserves harvested energy. Its ability to start up from as low as 140mV allows for operation even in low-light or low-thermal gradient conditions. The integrated cold-start and battery protection features reduce the need for external supervisory components, saving PCB real estate.

Applications

Getting Started

Engineers should begin by evaluating the AEM00300 using the 2AAEM003000000 evaluation board to test specific storage and source configurations. Configuration is handled through hardware pins to set the source voltage levels and battery protection thresholds without requiring complex firmware. Ensure that the storage element (battery or super-capacitor) is selected to match the discharge profile of the intended application.
