BQ29700DSER TI Battery Protection IC | 6-WSON (1.5X1.5) | 1-Cell Li-Ion, Overcurrent Protection

Product Overview

The BQ29700DSER from Texas Instruments is a single-cell lithium-ion battery protection IC designed to prevent overcharge, overdischarge, and overcurrent conditions. Housed in a compact 6-pin WSON package (1.5mm x 1.5mm), it offers a low quiescent current of typically 1.5µA in normal operation and 0.5µA in standby mode. The device integrates a precision voltage reference and a current sense circuit, providing accurate protection thresholds. It is ideal for space-constrained portable applications requiring reliable battery safety.
