e-peas Unveils Energy Harvesting PMICs for Remotes and Keyboards at CES 2024

Louvain-La-Neuve, Belgium – Jan 8, 2024 – At CES 2024, e-peas, the leading supplier of energy harvesting ICs, announced new additions to its Ambient Energy Managers family, optimized for Remote-Control Units (RCU) and Wireless Keyboards (KBD) design.

Key Features of AEM00920 & AEM10920

The newly introduced Energy Harvesting PMICs, AEM00920 & AEM10920, integrate advanced features to maximize energy transfer from Photovoltaic (PV) cells, efficiently store energy, and deliver reliable power for application circuitry.

High-Efficiency Energy Conversion

These innovative PMICs achieve up to 95% energy conversion efficiency from the harvester to the storage element. AEM00920 is optimized for PV cells featuring constant voltage regulation between 0.25V and 3.2V, while AEM10920 is optimized for PV cells with light-dependent maximum power point tracking (MPPT), ranging from 0.25V to 3.2V, with a configurable MPPT ratio from 35% to 90%.

Storage Element Protection and Quick Charge Boost

Storage elements like Hybrid Lithium capacitors, small Lithium-Ion batteries, or even triple NiMH cells are protected by dedicated mechanisms implemented in these PMICs. Both devices include a specific 5V boost circuitry, allowing designers to add a quick charge boost function to their product designs.

Efficient Energy Conversion for Applications

On the application side, both AEM00920 & AEM10920 provide an efficient energy conversion path thanks to the integrated buck DC-DC converter. GPIO configuration enables easy output voltage selection with an output voltage range of 2.2V, 2.5V, or 2.8V, interfacing the most recent connectivity chipsets. Both PMICs offer ultra-low cold-start, allowing applications to start even in low light conditions.

New Control and Configuration Features

New control and configuration features include a shipping mode to protect the storage element from being drained during shipment. The high level of integration in both ICs simplifies system development and minimizes the bill-of-materials.

Availability and Contact Information

Both AEM00920 and AEM10920 are available in a 24-pin QFN package with a board footprint of 4×4 sqmm. AEM00920 is available for sampling now, with AEM10920 expected later in January 2024. For sample requests and information about the evaluation boards, please visit www.e-peas.com/contact.
