e-peas – AEM Product Family (Ambient Energy Manager)

The AEM is an integrated energy management circuit that extracts DC or AC power from different types of ambient energy harvesters to simultaneously store energy in a rechargeable element and supply your system with two independent regulated voltages.

The AEM family enables you to extend the battery lifetime and ultimately eliminates the primary energy storage element in a large range of wireless applications such as industrial IoT, retail, smart home, cattle monitoring and wireless sensor nodes.
