The AEM13920 is a 2-input device for harvesting from independent photovoltaic (PV) and/or thermoelectric sources. The PMIC contains the storage element charge management circuitry, a high-efficiency buck converter to ensure correct delivery of this stored energy to your application, and a 5-V CCV charging circuit that can be used as a backup if the ambient energy sources are not quite enough to keep your device going – an example backup supply is USB charging. This is a great fit for asset tracking devices, electronic shelf labels, IoT sensors, and more.
Also featuring a backup charging circuit, the AEM00920 has been specially optimised to serve remote controls and keyboards. This single-input boost converter PMIC aims to eliminate the need for a primary battery in standard remote controls, replacing it with a Li-ion capacitor charged via a PV cell. Such an innovation eliminates the rolling cost of batteries to the consumer, as well as waste in a world where batteries are constantly going unrecycled even if they can be.
