Highly Versatile, Regulated Single-Output, Buck-Boost Ambient Energy Manager for Vibration Sources with Optional Primary Battery
E-peas’ low-frequency AC sources energy harvesting IC solution – The AEM30330 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 AEM30330 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.
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 with optional primary battery
Switches automatically between boost, buck-boost and buck operation, to maximize energy transfer from its input to the output
Automatically selects between the source, storage element and an optional primary battery
Automatically select the output between the system, the load and the storage element
Load supply voltage
Current drive capability: 30 mA in low power mode, 60 mA in high power mode
Selectable load voltage from 1.2 V to 3.3 V
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
Three capacitors: one 10 μF, one 15 μF, one at least 40 μF
