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.
Features:
– Ultra-low-power start-up: Cold start from -19 dBm
– 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
