BQ294702DSGR TI Battery Protection IC | 8-WSON (2x2) | 1-Cell, Overvoltage Protection

Product Overview

The BQ294702DSGR from Texas Instruments is a highly integrated, single-cell lithium-ion battery protection IC designed to prevent overvoltage conditions. It monitors cell voltage and provides a logic-level output to control an external FET for disconnecting the battery from the load or charger. Housed in a compact 8-WSON (2x2) package, it is ideal for space-constrained applications requiring reliable battery safety.
