BQ25308RTER TI Battery Charger IC | 16-WQFN (3x3) | I2C, 1-2 Cell Li-Ion

Product Overview

The BQ25308RTER from Texas Instruments is a highly integrated, I2C-controlled 1-cell to 2-cell Li-Ion battery charger IC designed for space-constrained applications. Housed in a compact 16-WQFN (3x3 mm) package, it supports fast charging with programmable charge current up to 3A and charge voltage up to 8.4V. The device features high accuracy voltage regulation (±0.5%) and current regulation (±5%), along with thermal regulation and protection. It operates from a wide input voltage range of 3.9V to 13.5V, making it suitable for USB and adapter inputs. The BQ25308RTER integrates power path management, allowing the system to run even with a deeply discharged battery.
