AEM00330 DATASHEET Highly Versatile Buck-Boost Ambient Energy Manager 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
-Automatically selects between the source, storage element
-Automatically select the output between the internal
supply, 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 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 The AEM00330 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 AEM00330 allows to extend
battery lifetime and ultimately eliminates the primary energy
storage element in a large range of applications.
Two different storage elements can be connected: one for
storing energy and another one for coupling the load output
voltage. At start-up, user can choose to charge the storage …
