AEM00300 Image

The AEM00300 from e-peas is a Buck-Boost Ambient Energy Manager Battery Charger that is designed to extract DC power from an ambient energy harvesting source and store the energy in a storage element. It extends battery lifetime by eliminating the primary energy storage element in a large range of applications. This PMIC has a selectable input voltage of 140 mV-4.5 V and is optimized for intermittent and pulse power. With its unique cold start circuit, the AEM00300 can start harvesting with an input voltage as low as 275 mV and from an input power of 3 μW. It has preset protection levels that determine the storage element voltages and provides protection thresholds to avoid over-charging and over-discharging the storage element.

The AEM00300 consists of a dual cell super-capacitor balancing circuit, one 10 µH inductor, and 10 and 15 µF capacitors. It is available as a surface-mount package that measures 4 x 4 mm and is ideal for indoor access systems, smart wearable sensors, smart switches for home/building, and Point of Sales (POS) applications.
