BQ25504RGTR

Power Management - Specialized Overview

The BQ25504RGTR is an ultra-low power boost converter and charger IC designed for energy harvesting applications. It operates with a quiescent current of less than 330 nA, enabling continuous energy collection from input voltages as low as 80 mV. The device supports cold start functionality at input voltages greater than 330 mV. It features programmable dynamic maximum power point tracking (MPPT) to optimize power extraction from sources such as photovoltaic or thermal electric generators. The component manages stored energy in lithium-ion, lithium polymer, supercapacitors, and other battery types within a VQFN-16 package.

Power Management - Specialized Procurement Notes

Verify the specific suffix RGTR against official Texas Instruments documentation to confirm the reel packaging configuration and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the VQFN-16 package. Confirm that the selected variant meets all required operating temperature ranges and humidity sensitivity levels for the intended deployment environment before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when designing systems that require harvesting micro-watt to milli-watt power from ambient sources. It is suitable for applications demanding minimal static current draw to maximize operational lifetime. Consider its MPPT capabilities if the energy source exhibits variable output characteristics. Evaluate the available input voltage range against the specific generator's output profile to ensure reliable cold-start performance.
