AEM00300 DATASHEET Highly Versatile Buck-Boost Ambient Energy Manager Battery Charger
with Source Voltage Level Configuration
Feature Description Ultra-low power start-up -Cold start from 275 mV input voltage and 3 µW input power
(typical) Constant input voltage regulation -Optimized for intermittent and pulse power
-Selectable operating input voltage from 140 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 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 three external components are required
-One 10 µH inductor
-Two capacitors: one 10 µF, one 15 µF The AEM00300 is an integrated energy management circuit
that extracts DC power from an ambient energy harvesting
source to store energy in a storage element. The AEM00300
allows to extend battery lifetime and ultimately eliminates the
primary energy storage element in a large range of
applications.
Thanks to its selectable operating input voltage, it is possible to
set a voltage at which the AEM00300 operates. This voltage is
between 140 mV and 4.5 V.
With its unique cold start circuit, the AEM00300 can start
harvesting with an input voltage as low as 275 mV and from an
input power of 3 μW. The preset protection levels determine …
