Expanding its portfolio of advanced power management ICs (PMICs) for energy harvesting applications, e-peas has announced two new devices capable of further pushing the performance envelope. The RF AEM30330, Vibration AEM30330, and Solar AEM10330 PMICs both utilize a buck-boost architecture. This enables them to cover a greater range of input voltage levels (from 100mV to 4.5V), meaning that both low and high power sources can be addressed. The AEM30330 is targeted at RF/vibration-oriented deployments (including industrial equipment, home automation systems, healthcare monitoring, and household appliances), while the AEM10330 is specifically intended for solar deployments (with the scope to manage up to 7 connected photovoltaic cells).
Enhanced Energy Management
The new e-peas PMICs deliver a maximum current of 60mA, allowing storage elements such as supercapacitors to be charged rapidly. Their adaptive energy management capabilities enable them to automatically switch between boost, buck-boost, and buck operational configurations as deemed appropriate. This ensures that optimal energy transfer is always maintained between the respective inputs and outputs of these devices.
Superior Cold-Start Threshold
Another key aspect is the cold-start threshold at which an AEM30330/AEM10330-based system can begin to draw energy from the surrounding environment. This has been lowered to just 275mV/3µW, a substantial improvement over the previous generation of e-peas PMICs, and is unmatched by any other solution currently on the market.
Maximizing Power Point Tracking
By leveraging the fully configurable maximum power point tracking (MPPT) function, the AEM30330 and AEM10330 are able to constantly monitor and regulate the input with a 20ms refresh rate. This ensures the extraction efficiency of the system remains as high as possible, regardless of variations in the input from the source. These PMICs have a working temperature range from -40°C to 125°C. They are supplied in compact 40-pin QFN packages and require only minimal passive components. This translates into a solution with an ultra-low bill-of-materials which takes up very little board space. Over-charge and over-discharge protection mechanisms are also incorporated.
Versatility and Superior Performance
“Since the release of the initial AEM series PMICs back in 2017, e-peas has been differentiating itself from the other players in the energy harvesting sector through products with superior performance characteristics, alongside exceptional application knowledge,” says Christian Ferrier, Marketing Director at e-peas. “With these latest additions to the series, we are significantly increasing the pervasiveness of our technology, allowing a broader variety of use cases to benefit from it.”
