BQ24120RHLTG4 TI Battery Charger IC | 20-VQFN (3.5x4.5) | 4.5V-10V Input, 1.25A Charge

Product Overview

The BQ24120RHLTG4 is a highly integrated Li-ion and Li-polymer linear battery charger IC from Texas Instruments, designed for space-constrained portable applications. It operates from a 4.5V to 10V input voltage range and supports a programmable charge current up to 1.25A. The device is housed in a compact 20-pin VQFN package (3.5mm x 4.5mm) with thermal pad for enhanced heat dissipation. It features a dynamic power-path management (DPPM) that allows the system to be powered directly from the input while simultaneously charging the battery, reducing battery cycling and enabling instant-on operation even with a deeply discharged battery.
