HS6400 BQ25570 Energy Harvester Module Step Up Boost Charger and Buck Converter Module Low Power
Product features:
1. Power consumption DC-DC boost charger Cold start voltage: VIN>330mVVIN100 mV Continuous energy harvesting Input voltage regulation High impedance input source collapse Complete operation Static current is 488nA (typical value) Transport mode with battery power<5 nA
2. Energy storage can be stored in rechargeable lithium-ion batteries, thin-film batteries, battery capacitors, or conventional capacitors
3. User programmable overvoltage level for internal settings of battery charging and protection
4. The microcontroller with programmable threshold and hysteresis warning connected to the battery good output flag can be used to enable or disable system loads in case of imminent power outage
5. Programmable voltage reduction and stabilization output (voltage reduction) efficiency up to 93%, supporting peak output current up to 110mA (typical value)
6. Programmable High Power Point Tracking (MPPT) provides energy extraction from various energy harvesters including solar panels, thermal energy, and piezoelectric generators
Description:
The BQ25570 device is specially designed to effectively extract micro watts (W) to milliwatts (mW) of power generated by various high output impedance DC power sources, such as photovoltaic power sources (solar energy) or thermal generators (TEG), without folding these power sources. The battery management function ensures that rechargeable batteries will not be overcharged due to extracted power, and the voltage will not rise or deplete due to system load, exceeding the limit. In addition to the boost charger, bq25570 also integrates a high-power load buck converter, which can provide a second power rail for systems such as wireless sensor networks (WSN) with strict power and operational requirements. All functions of bq25570 are packaged in a small footprint 20 lead 3.5mmx3.5mm QFN package (RGR)
