Description
The bq25505 device is specifically designed to efficiently extract the microwatts (µW) to miliwatts (mW) of power generated from a variety of DC energy harvesting, high-impedance sources like photovoltaic (solar) or thermal electric generators (TEGs) without collapsing those sources.
Features
- 1 Ultra Low-Power With High-Efficiency DC-DC Boost Charger.
- Cold-Start Voltage: VIN ≥ 600 mV.
- Continuous Energy Harvesting From Input
Sources as Low as 100 mV.
- Ultra-Low Quiescent Current of 325 nA.
- Input Voltage Regulation Prevents Collapsing High-Impedance Input Sources.
- Ship Mode With < 5 nA From Battery.
- Energy Storage.
- Energy can be Stored to Rechargeable Li-Ion Batteries, Thin-Film Batteries, SuperCapacitors, or Conven.
