Highly efficient, Regulated Dual-Output, Ambient Energy Manager for Source Voltage Level Configuration with Optional Primary Battery
The AEM00940 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 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.
