BQ25570EVM in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ25570EVM series from Texas Instruments is a specialized evaluation module designed for the BQ25570 nano-power energy harvesting and management integrated circuit. This platform allows engineers to extract microwatts to milliwatts of power from high-impedance sources like solar, thermal, or vibration transducers. It integrates a highly efficient boost charger with a nanopower buck converter, providing a complete power management solution for charging storage elements and regulating an output voltage for ultra-low-power microcontrollers and sensors.
Variants in This Sub-Family
The BQ25570EVM family typically centers around the -206 variant, which serves as the primary reference design for the BQ25570 IC. Variants within the broader BQ24xxx/BQ25xxx evaluation ecosystem differ based on the specific power management strategy, such as whether they include an integrated buck regulator (like the BQ25570) or focus solely on high-efficiency boost charging for larger storage elements (like the BQ25504 or BQ25505).
