AEM10940 is a power management IC designed by e-peas to store power from photovoltaics (PVs) cells and thermoelectric generator (TEGs) into rechargeable power sources, such as Li-Ion batteries and thin film batteries. At the same time, it supplies the system with two different regulated voltages, the charging voltage and the system supply voltage.
e-peas is a startup based in Liège, Belgium. It works towards solutions to extend batteries life-time for IoT applications, by increasing the amount of harvested energy and reducing power consumption for each element in the system.
The AEM10940 features are:
- Ultra low power start-up, which gives it the ability to operate with just 380 mV input voltages and 1 μW input power.
- Ultra-low-power Boost regulator, whit operates with input voltages in a range of 100 mV to 2.5 V.
- Integrated Low Drop-Out (LDO) regulator, drives a microcontroller at 1.8 V with up to 10 mA load current at low voltage supply, and drives a radio transceiver at configurable voltage from 2.2 V to 4.2 V with 80 mA load current.
- Programmable overcharge and overdischarge protection
- Suitable for any type of rechargeable battery or supercapacitor
e-peas introduces AEM10040 as an evaluation board that provides a laboratory-like environment for testing and analysing. It also simplifies the connections with power sources, storage elements, and the different loads. However, the evaluation board is not suitable for end-user applications.
