BQ25570RGRT TI Power Management IC | 20-VQFN (3.5X3.5) | Boost Charger, Nano-Power

Product Overview

The BQ25570RGRT from Texas Instruments is a highly integrated energy harvesting power management IC designed for ultra-low power applications. It features a boost charger with maximum power point tracking (MPPT) and a nano-power buck converter, enabling efficient energy extraction from various DC sources such as solar cells, thermoelectric generators, and piezoelectric transducers. The device operates with a quiescent current of only 330 nA, making it ideal for battery-less or energy harvesting systems. Housed in a compact 20-VQFN (3.5x3.5 mm) package, it provides a complete power management solution for space-constrained designs.
