Description:

The bq25570 device is specifically designed to efficiently extract microwatts (µW) to milliwatts (mW) of power generated from a variety of high output impedance DC sources like photovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources. The battery management features ensure that a rechargeable battery is not overcharged by this extracted power, with voltage boosted, or depleted beyond safe limits by a system load. In addition to the highly efficient boosting charger, the bq25570 integrates a highly efficient, nano- power Loads buck converter for providing a second power rail to systems such as wireless sensor networks (WSN) which have stringent power and operational demands. All the capabilities of bq25570 are packed into a small foot-print 20-lead 3.5-mm x 3.5-mm QFN package (RGR).

Applications:

Energy Harvesting

Solar Chargers

Thermal Electric Generator (TEG) Harvesting

Wireless Sensor Networks (WSN)

Low Power Wireless Monitoring

Environmental Monitoring

Bridge and Structural Health Monitoring (SHM)

Smart Building Controls

Portable and Wearable Health Devices

Entertainment System Remote Controls

Package includes:

1 x CJMCU-2557 BQ25570 Nano Power Boost Charger

CJMCU-2557-BQ25570-Nano-Power-Boost-Charger-and-Buck-Converter-for-Energy-Harvester-Powered-Applicat-1295684
