Product Description

Thermal or power harvesting battery charger w/ extra buck converter
The gadget is designed to effectively extract microwatts (µW) to milliwatts (mW) of energy generated from a wide range of excessive output impedance DC sources like photovoltaic (photo voltaic) or thermal electrical mills (TEG) with out collapsing these sources. The battery administration options be certain that a chargeable battery shouldn’t be overcharged by this extracted energy, or depleted past protected limits by a system load.
Along with the extremely environment friendly boosting charger, the bq25570 integrates a extremely environment friendly, nano- energy buck converter for offering a second energy rail to methods equivalent to wi-fi sensor networks. Output voltage from this converter is about at 3.3V.
Extremely Low Energy DC-DC Increase Charger
Chilly-start Voltage: VIN ≥ 330 mV
Steady Power Harvesting From VIN as little as 100 mV
Enter Voltage Regulation Prevents Collapsing Excessive Impedance Enter Sources
Full Working Quiescent Present of 488 nA
Power Storage
Power might be Saved to Re-chargeable Li-ion Battery, Tremendous- capacitors or Standard Capacitors
Battery Charging and Safety
Internally Set Undervoltage Degree
Consumer Programmable Overvoltage Ranges
Battery Good Output Flag
Programmable Threshold and Hysteresis
Warn Connected Microcontrollers of Pending Lack of Energy
