TI BQ25505RGRR

能量收集325nA0.12V ~ 4V

Overview

All trademarks are the property of their respective owners.

The bq25505 device is specifically designed to efficiently extract the microwatts (μW) tomiliwatts (mW) of power generated from a variety of DC energy harvesting, high-impedance sourceslike photovoltaic (solar) or thermal electric generators (TEGs) without collapsing those sources.The battery-management features of the bq25505 ensure that a secondary rechargeable battery is notovercharged by this extracted power, with voltage boosted, nor depleted beyond safe limits by asystem load. The integrated multiplexer gate drivers autonomously switch the system load to aprimary nonrechargeable battery if the secondary battery voltage falls below the user-definedVBAT_OK threshold.
