Datasheet AEM00330 (E-peas)

DATASHEET AEM00330 Highly Versatile Buck-Boost Ambient Energy Manager with Source Voltage Level Configuration Feature Description
Ultra-low power start-up The AEM00330 is an integrated energy management circuit - Cold start from 275 mV input voltage and 3 µW input power that extracts DC power from an ambient energy harvesting (typical) source to simultaneously supply an application and store Constant input voltage regulation energy in a storage element. The AEM00330 al ows to extend battery lifetime and ultimately eliminates the primary energy - Optimized for intermittent and pulse power storage element in a large range of applications. - Selectable operating input voltage from 140 mV to 4.5 V Two different storage elements can be connected: one for Adaptive and smart energy management storing energy and another one for coupling the load output - Switches automatical y between boost, buck-boost and voltage. At start-up, user can choose to charge the storage buck operation, to maximize energy transfer from its input element first or the load capacitor first. to the output - Automatical y selects between the source, storage element Thanks to its selectable operating input voltage, it is possible to set a voltage at which the AEM00330 operates. This voltage is - Automatical y select the output between the internal between 140 mV and 4.5 V. supply, the load and the storage element Load supply voltage With its unique cold start circuit, the AEM00330 can start harvesting with an input voltage as low as 275 mV and from an - Current drive capability: 30 mA in low power mode, 60 mA input power of 3 μW. The preset protection levels determine in high power mode the storage element voltages protection thresholds to avoid - Selectable load voltage from 1.2 V to 3.3 V over-charging and over-discharging the storage element and Battery protection features thus avoiding damaging it. Those are set through configuration - Selectable over-charge and over-discharge protection for pins. Moreover, special modes can be obtained at the expense any type of rechargeable battery or (super-)capacitor of a few configuration resistors. - Fast super-capacitor charging The load voltage can be selected to cover most application - Dual cel super-capacitor balancing circuit needs, with a maximum available load current of 60 mA. Smal est footprint, smal est BOM - Only four external components are required - One 10 µH inductor
Applications
- Three capacitors: one 10 µF, one 15 µF, one at least 47 µF • Door access systems • Smart wearable sensors • Smart switches home/building • Point-of-sales (POS) CSRC LDCDC
