e-peas AEM PMIC - Solid State Supplies

Posted on

Ambient Energy Manager PMIC Family

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 monitoring, geolocation, home automation, tracking and wireless sensor nodes.
