What are the key features of BQ25570?
- Integrated boost charger with MPPT harvests energy from solar, thermoelectric, and piezoelectric sources starting at 100 mV cold-start
- Programmable MPPT ratio and output voltage via external resistors enabling flexible energy-harvesting system design
- Ultra-low 488 nA quiescent current maximizes energy efficiency in always-on wireless sensor nodes
- Integrated buck converter with programmable output voltage for directly powering MCUs and sensors from the storage element
What is BQ25570 used for?
BQ25570 is the core power management IC for batteryless and energy-autonomous wireless sensor nodes that harvest ambient energy from photovoltaic cells, thermoelectric generators, or piezoelectric transducers in industrial monitoring, precision agriculture, and smart building applications. Its cold-start capability from 100 mV allows operation from extremely weak energy sources such as indoor light or body heat, enabling perpetually powered IoT endpoints without battery replacement. The integrated MPPT and buck converter reduce BOM count and PCB area in wearable health sensors, RFID tags, and structural health monitoring systems.
