BQ24308DSGR TI Battery Protection IC | 8-WSON (2x2) | Overvoltage, Overcurrent

Product Overview

The BQ24308DSGR from Texas Instruments is a highly integrated, single-cell lithium-ion battery protection IC designed to prevent damage from overvoltage, overcurrent, and short-circuit conditions. Housed in a compact 8-WSON (2x2) package, it offers a complete protection solution for space-constrained portable applications. The device features a low on-resistance (50 mΩ typical) N-channel MOSFET switch, ensuring minimal power dissipation and efficient operation. With a fixed overvoltage threshold of 4.35 V and adjustable overcurrent limit via an external resistor, the BQ24308DSGR provides flexible and reliable protection for Li-Ion batteries.
