Highly efficient, Regulated Dual-Output, Ambient Energy Manager for Source Voltage Level Configuration with Optional Primary Battery
The AEM00940/1 is an integrated energy management circuit that extracts DC power to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. The AEM00940 allows to extend battery lifetime and ultimately eliminates the primary energy storage element in a large range of source such as pulse source, intermittent source, capacitive source and constant MPP source.
The AEM00940/1 harvests the available input current up to 110mA while regulating the source at a voltage that is configured by the user. It integrates an ultra-low power boost converter to charge a storage element, such as a Li-ion battery, a thin film battery, a supercapacitor or a conventional capacitor.
