TEXAS INSTRUMENTS BQ25505RGRT 芯片, 升压稳压充电器, 锂离子/薄膜, VQFN-20
The is an ultra low power harvester Power Management IC with boost charger and autonomous power multiplexer. It is specifically designed to efficiently extract the microwatts µW to milliwatts 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. The battery-management features of the BQ25505 ensure that a secondary rechargeable battery is not overcharged by this extracted power, with voltage boosted, nor depleted beyond safe limits by a system load. The integrated multiplexer gate drivers autonomously switch the system load to a primary non-rechargeable battery if the secondary battery voltage falls below the user-defined VBAT_OK threshold.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
