AEM10941 – Energy Harvesting Power Management IC


E-peas’ photovoltaic energy harvesting IC solution – AEM10941 – is the next generation integrated energy management subsystem that extracts DC power from up to 7 cells solar panels to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the primary energy storage element in a large range of wireless applications like industrial monitoring, home automation, wearables.



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 V

Integrated 1.2/1.8 V LDO regulator:

  • Up to 20 mA load current
  • Power gated dynamically by external control
  • Selectable output voltage

Integrated 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 voltage

Flexible 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

Smallest footprint, smallest BOM:

  • Only seven passive external components

Optional primary battery:

  • Automatically switches to the primary battery when the secondary battery is exhausted

Integrated balun for dual-cell supercapacitor
