BQ296215DSGR

Battery Management Overview

The BQ296215DSGR is a battery protection integrated circuit from Texas Instruments designed for lithium-ion systems. It provides overvoltage protection for 2-series to 4-series cell configurations. The device operates within a supply voltage range of 3 V to 20 V and features an integrated low-dropout regulator (LDO) outputting 3.3 V at 2 mA. It utilizes an 8-pin WSON package, supports surface-mount installation, and functions across a temperature range of -40°C to +110°C with a quiescent current of 1 µA.

Battery Management Feature Summary

• Provides hardware-based overvoltage protection for multi-cell lithium-ion battery packs
• Integrates a regulated LDO power supply for auxiliary circuitry
• Operates in high-temperature environments suitable for industrial applications

Battery Management Applications

• Portable electronic devices requiring multi-cell battery management
