BQ296909DSGR TI Battery Protection IC | 8-WSON (2x2) | 4.35V OVP, 3A

Product Overview

The BQ296909DSGR is a highly integrated, single-cell lithium-ion battery protection IC from Texas Instruments. It provides overvoltage protection (OVP), undervoltage protection (UVP), and overcurrent protection (OCP) in a compact 8-WSON (2x2) package. Designed for space-constrained applications, it offers a fixed overvoltage threshold of 4.35V and supports continuous discharge currents up to 3A. The device features low quiescent current (typical 1.5µA) and a built-in delay timer to prevent false triggering.
