The BQ25570RGRR from Texas Instruments is an ultra-low power harvester power management IC designed for energy harvesting applications. This device integrates a boost charger and a nanopower buck converter, enabling efficient power management from various energy sources.
Key electrical specifications include a minimum input voltage of 0.6V and a maximum input voltage of 5.1V, with an absolute maximum of 5.5V. The battery charge voltage ranges from 2.2V to 5.5V, and the maximum charge current is 0.1A. It operates with a low quiescent current of 488 nA typical and a ship mode current below 5 nA. The buck converter offers a typical peak output current of 110 mA with high efficiency up to 93%.
This IC supports continuous energy harvesting from input voltages as low as 0.1V and features programmable maximum power point tracking (MPPT) for optimal energy extraction from sources like solar panels, thermal, and piezoelectric generators. It also includes input overvoltage protection and user-programmable overvoltage levels for battery protection.
The BQ25570RGRR is housed in a 20-VQFN package with a 3.5mm x 3.5mm footprint and is designed for surface mounting. It operates within a temperature range of -40°C to 125°C.
