Product details

325 nA quiescent – cold-start from micro-watt sources

The BQ25505RGRT is an energy-harvesting PMIC from Texas Instruments designed to extract usable power from low-voltage, low-current sources. Its 325 nA typical supply current sets the floor for the minimum source power the boost converter can cold-start from — a photovoltaic cell delivering tens of micro-watts under dim indoor light is enough to begin charging. The input operates from 0.12 V up to 4 V, covering the typical open-circuit voltage of a single solar cell or thermoelectric generator (TEG). The controller manages the energy storage element — a rechargeable battery or supercapacitor — while protecting against over-voltage on the storage node.

Frequently asked questions

How can I order BQ25505RGRT or check stock?

Submit an RFQ with your target quantity — our sourcing desk will confirm current pricing and lead time against your BOM line. No stock-holding claim is made here; availability is verified per inquiry.

Does BQ25505RGRT work with solar energy harvesting?

Yes — the 0.12 V to 4 V input range covers the output of a single photovoltaic cell under varying light. The 325 nA quiescent current allows the controller to start charging from the cell's micro-watt output even in low indoor light.
