Compact Ultra-Efficient Solar/Light Energy Harvesting Battery Charger for Wearable and Medical applications
The AEM10900 is a fully integrated and compact battery charger circuit that extracts DC power from a solar cell to store energy in a rechargeable battery. This compact and ultra- efficient battery charger allows to extend battery lifetime and eliminates the primary energy storage in a large range of wireless application, such as wearable and medical applications and Smart sensors. Thanks to its Maximum Power Point Tracking and its ultra-low power boost converter, the AEM10900 harvests the maximum available input power from a source to charge a storage element, such as a Li-ion battery. The boost converter operates with input voltages in a range from 115 mV to 1.5 V. With its unique cold-start circuit, it can start operating with an input voltage as low as 250 mV and an input power of only 5 μW. The output voltages are in a range of 2.8 V to 4.8 V.
