AEM00900/1 
Photovoltaic Harvesting Battery Charger

Compact PMIC with Source Voltage Level Configuration for Pulsed Energy Sources

AEM00900/1 is an integrated energy management circuit that extracts energy from random pulses and stores it in a storage element. The AEM00900/1 allows to eliminates the primary energy storage element for applications using  pulse source, intermittent source of fast variation and random time availability. Typical applications include wall switches, remote control, detectors door/ windows opening in smart home or smart building . The boost converter operates with input voltages ranging from 120 mV to 1.5 V. The unique architecture transfers energy from the pulsed source to a storage element when rising above a low threshold voltage that is pre defined. 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.
