Ultra Efficient Dual Sources Energy Manager with Ratio/Constant Voltage Regulation, Regulated Buck Output and 5 V Charger, 120 mV, 135 mA The AEM13921 is a fully integrated and compact power management circuit that extracts DC power from two harvesting sources to store energy in a rechargeable storage element and supply an application circuit. A 5 V input can also be used to charge the storage element (e.g., if it gets depleted). This compact and ultra-efficient PMIC allows for extending battery lifetime and eliminating the primary energy storage in a large range of applications. Both sources implement Maximum Power Point Tracking (MPPT) based on open-circuit voltage ratio as well as constant source voltage regulation features, allowing for harvesting the maximum power available from each source to charge the storage element. With its unique cold-start circuit, it can start operating with an input voltage as low as 275 mV (min. 1.5 µW power). The configurable protection thresholds prevent overcharging and overdischarging the storage element. No external components are required to set those thresholds. The thermal monitoring prevents charging and discharging the storage element outside a configurable temperature range. The Average Power Monitoring (APM) allows the application circuit to get an estimate of the energy harvested from each source to the battery and from the battery to the application circuit. A shipping mode is available to avoid charging and discharging the storage element during shipping or storage. A buck regulator with selectable output voltage allows an application circuit to be supplied with high efficiency. I²C communication allows users to control every setting of the AEM13921 from the application circuit MCU.
