BQ29701DSET TI Battery Protection IC | 6-WSON (1.5X1.5) | Overcharge/Overdischarge Protection

Product Overview

The BQ29701DSET from Texas Instruments is a highly integrated, single-cell lithium-ion battery protection IC designed to prevent overcharge, overdischarge, and overcurrent conditions. Housed in a compact 6-WSON (1.5x1.5mm) package, it offers a low quiescent current of typically 1.5µA, making it ideal for space-constrained and power-sensitive portable applications. The device monitors battery voltage and current, and controls an external N-channel MOSFET to disconnect the battery from the load or charger when fault conditions occur.
