e-peas‘ AEM30300 is an integrated energy management circuit that extracts DC power from an ambient energy harvesting source to store energy in a storage element.
The AEM30300 allows to extend battery lifetime and ultimately eliminates the primary energy storage element in a large range of wireless applications, such as industrial monitoring, geolocation, home automation, e-health monitoring and wireless sensor nodes.
Thanks to its Maximum Power Point Tracking system, the AEM30300 extracts the maximum energy available from the source. It integrates an ultra-low power DCDC converter which operates with input voltages ranging from 100 mV to 4.5 V.
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 Point Tracking (MPPT)
- Selectable open-circuit voltage ratios from 35% to 80% or fixed impedance
- Programmable MPPT sensing period
- MPPT voltage operation range from 100 mV to 4.5 V
Adaptive and smart energy management
- Switches automatically between boost, buck-boost and buck operation, to maximize energy transfer from its input to the output
Battery protection feature
- 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
- Two capacitors: one 10 μF, one 15 μF
