Description

The BQ25505RGRT 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.
Input voltage regulation prevents collapsing high-impedance input sources
Battery charging and protection
Internally set undervoltage level
User-programmable overvoltage level
Battery-good output flag
Programmable threshold and hysteresis
Warn attached microcontrollers of pending loss of power
Can be used to enable or disable system loads
Programmable maximum power point tracking
Green product and no Sb/Br
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.
