The AEM10941 is an integrated energy management circuitthat extracts DC power from up to 7-cell solar panels to si-multaneously store energy in a rechargeable element and sup-ply the system with two independent regulated voltages. TheAEM10941 allows to extend battery lifetime and ultimatelyeliminates the primary energy storage element in a large rangeof wireless applications, such as industrial monitoring, geoloca-tion, home automation, e-health monitoring and wireless sen-sor nodes.


  • Ultra-low power start-up: Cold start from 380 mV input voltage and 3 μW input power (typical)Ultra-low power boost regulator: Open-circuit voltage sensing for MPPT every 5 s Configurable MPPT with 2-pin programming Selectable Voc ratios of 70, 75, 85 or 90 % Input voltage operation range from 50 mV to 5 V MPPT voltage operation range from 50 mV to 5 VIntegrated 1.2/1.8 V LDO regulator: Up to 20 mA load current Power gated dynamically by external control Selectable output voltageIntegrated 1.8 V-4.1 V LDO regulator: Up to 80 mA load current with 300 mV drop-out Power gated dynamically by external control Selectable or adjustable output voltageFlexible energy storage management: Selectable overcharge and overdischarge protection For any type of rechargeable battery or (super)capacitor Fast supercapacitor charging Warns the load when battery is running low Warns when output voltage regulators are available
