AEM00940 DATASHEET Highly efficient, regulated dual-output, ambient energy manager for
Source Voltage Level Configuration with optional primary battery
Features Description The AEM00940 is an integrated energy management circuit
that extracts DC power to simultaneously store energy in a
rechargeable element and supply the system with two
independent regulated voltages. The AEM00940 allows to
extend battery lifetime and ultimately eliminates the primary
energy storage element in a large range of source such as
pulse source, intermittent source, capacitive source and
constant MPP source. Ultra-low power start-up: -Cold start from 380 mV input voltage and 3 µW input
power (typical) Constant input voltage regulation: -Optimized for intermittent and pulse power
-Selectable operating input voltage from 50 mV to
4.5V
-Up to 110 mA current extracted from the harvester The AEM00940 harvests the available input current up to
110 mA while regulating the source at a voltage that is
configured by the user. It integrates an ultra-low power boost
converter to charge a storage element, such as a Li-ion
battery, a thin film battery, a supercapacitor or a
conventional capacitor. Integrated 1.2 V/1.8 V LDO regulator: -Up to 20 mA load current
-Power gated dynamically by external control
-Selectable output voltage Integrated 1.8 V -4.1 V LDO regulator -Up to 80 mA load current with 300 mV drop-out
-Power gated dynamically by external control
-Selectable or adjustable output voltage Thanks to its selectable operating input voltage, it is possible …
