BQ25570 Energy Harvester Module 110mA
The BQ25570 is an ultra-low-power energy-harvesting controller for weak DC sources, and specifically designed to efficiently extract microwatts (µW) to milliwatts (mW) of power generated from a variety of high output impedance DC sources such as solar panels, thermoelectric, piezoelectric, vibration, wind and electromagnetic generators.
It boosts and stores harvested energy in a rechargeable battery or supercapacitor, provides charging protection, prevents source collapse through input regulation, and includes an efficient buck converter for powering low-power sensors, wireless nodes and compact IoT devices.
