AEM10330 Power Management IC

E-peas’ solar energy harvesting IC solution – The AEM10330 is an integrated energy management circuit that extracts DC power from an ambient energy harvesting source to simultaneously supply an application and store energy in a storage element. The AEM10330 allows to extend battery lifetime and ultimately eliminates the primary energy storage element in a large range of applications, such as Asset tracking/monitoring, Industrial applications, Retail ESL/smart sensors, Aftermarket automotive systems, Smart home/building.

Key Features:

• Ultra-low-power start-up:
  • Cold start from 275 mV input voltage and 3 μW input power (typical)
• Very efficient energy extraction:
  • open-circuit voltage sensing for Maximum Power PointTracking (MPPT)
  • Selectable open-circuit voltage ratios from 60% to 90% orfixed impedance
  • Programmable MPPT sensing period-MPPT voltage operation range from 100 mV to 4.5 V
• Adaptive and smart energy management with optionalprimary battery
• Load supply voltage
  • Current drive capability: 30 mA in low power mode, 60 mAin high power mode
  • Selectable load voltage from 1.2 V to 3.3V
• Battery protection features
  • Selectable over-charge and over-discharge protection for any type of rechargeable battery or (super-)capacitor
  • Fast super-capacitor charging
  • Dual cell super-capacitor balancing circuit
• Smallest footprint, smallest BOM
  • Only four external components are required
  • One 10 μH inductor
  • Three capacitors: one 10 μF, one 15 μF, one at least 40μF

Applications:

• Asset Tracking/Monitoring
