BQ24715RGRR TI Battery Charger IC | 20-VQFN (3.5x3.5) | 1-4 Cell Li-Ion, 5A

Product Overview

The BQ24715RGRR is a highly integrated battery charger controller from Texas Instruments, designed for 1-4 cell Li-Ion and Li-Polymer battery packs. It features a programmable charge current up to 5A and supports a wide input voltage range from 4.5V to 24V. The device operates with high efficiency, up to 94%, and includes dynamic power management (DPM) to optimize charging based on system load. Housed in a compact 20-pin VQFN package (3.5mm x 3.5mm), it is ideal for space-constrained applications.
