BQ24171RGYR Description

Short technical summary and product information.

The Texas Instruments BQ24171RGYR is a highly integrated, standalone, switched-mode battery charger designed for 1 to 3 series Li-Ion or Li-Polymer cells. It supports a maximum charge current of 4A and operates within an input voltage range of 4.5V to 17V, with an absolute maximum rating of 20V.

 

Key features include JEITA-compatible battery temperature monitoring, hot/cold profile monitoring, and IC thermal regulation for safe operation. The device incorporates an automatic power path selector, allowing seamless switching between adapter and battery power. It also includes input overvoltage protection with a programmable threshold and dynamic power management.

 

Packaged in a 24-VQFN (5.5mm x 3.5mm) surface-mount package, the BQ24171RGYR is suitable for space-constrained applications. Its control interface is standalone and RC-settleable, simplifying integration into various designs. The charger offers adjustable battery charge voltage up to 15.5V and provides high efficiency up to 94% with a 1.6-MHz switching frequency.
