Product Description

The BQ25570RGRT is an ultralow-power harvester power management Integrated Circuit with boost charger and nano-power buck converter designed to efficiently extract microwatts (µW) to milliwatts (mW) of power generated from a variety of high output impedance DC sources like photovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources. The battery management features ensure that a rechargeable battery is not overcharged by this extracted power, with voltage boosted or depleted beyond safe limits by a system load. In addition to the highly efficient boosting charger, the BQ25570 integrates a highly efficient, nanopower buck converter for providing a second power rail to systems such as wireless sensor networks (WSN) which have stringent power and operational demands.
Ultra low power DC-DC boost charger
Input voltage regulation prevents collapsing high impedance input sources
488nA Full operating quiescent current
Internally set under-voltage level
User programmable overvoltage levels
Programmable threshold and hysteresis
Warn attached microcontrollers of pending loss of power
Can be used to enable or disable system loads
Programmable step down regulated output (buck)
High efficiency up to 93%
Programmable maximum power point tracking (MPPT)
Green product and no Sb/Br
This 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.
