e-peas extends its leadership in ultra-low power energy harvesting technology with the launch of the AEM13921, the newest member of the AEM1392x family. Building on the proven success of the AEM13920, the AEM13921 redefines system flexibility and energy management efficiency for multi-source harvesting applications.
Expanded Configuration & Performance Range
Compared to the AEM13920, the AEM13921 offers:
-
Higher load output voltage range up to 3.3 V
-
New protection thresholds and an additional ST_LOAD pin for proactive load shutdown alerts
Enhanced Energy Management with Dual Inputs
The AEM13921 integrates two independent boost inputs, enabling seamless energy harvesting from multiple sources. It achieves industry-leading source-to-storage efficiency, ensuring maximum power delivery even under low or variable input conditions.
Smarter Power Flow with Average Power Monitoring (APM)
The integrated Average Power Monitoring (APM) system measures power transfer between sources, storage elements, and loads in real time. This allows developers to:
- Estimate energy harvested and consumed
- Assess the state of charge of the storage element
- Implement adaptive and energy-aware application behaviors
- Optimize harvester algorithms for dynamic environments
With APM, the AEM13921 enables truly intelligent power management and opens new opportunities for self-learning, autonomous IoT systems.
Easy Evaluation & Configuration
The new AEM13921 Evaluation Board and I²C Configuration Tool accelerate design and testing:
- Configure and monitor all registers via an intuitive GUI
- Track source, storage, and load power in real time
- Experiment with different MPPT settings and protection thresholds
- Shorten development cycles while improving performance
AEM13921 – Powering the Future with Ambient Energy
Delivering smarter energy harvesting, finer control, and wider compatibility, the AEM13921 marks a major step forward for autonomous electronics.
