Frequently Asked Questions
What is the minimum input voltage for the BQ25505RGRR?
The BQ25505RGRR operates with a minimum input voltage of 0.6V, allowing it to harvest energy from very weak sources such as small solar cells in low-light conditions or thermoelectric generators with small temperature differentials. The maximum input voltage is 5.1V.
What types of energy sources can the BQ25505RGRR harvest from?
The BQ25505RGRR can harvest energy from a wide variety of ambient sources including photovoltaic (solar) cells, thermoelectric generators (TEGs), piezoelectric transducers, and RF energy harvesters. Its wide input voltage range of 0.6V to 5.1V and pulse frequency modulation control make it suitable for sources with variable or intermittent output.
What package is the BQ25505RGRR available in and what are the dimensions?
The BQ25505RGRR is housed in a 20-pin Quad Flat No-Lead (QFN) package, also identified by JESD-30 code S-PQCC-N20. The compact leadless package is designed for high-density PCB layouts in space-constrained IoT and wearable applications.
How does the autonomous power multiplexor work in the BQ25505RGRR?
The autonomous power multiplexor in the BQ25505RGRR automatically manages power routing between the energy harvesting source, the energy storage element (such as a rechargeable battery or supercapacitor), and the system load. It operates without requiring intervention from a host microcontroller, enabling true autonomous and ultra-low power operation in wireless sensor and IoT applications.
