Product details

Li-ion front-end protector with full fault coverage

The Texas Instruments BQ24311DSGT is a dedicated Li-ion battery protection IC that monitors and responds to overcurrent, overtemperature, overvoltage, and undervoltage fault conditions. It's designed to sit between the charger input and the battery cell, acting as a solid-state fuse and thermal cutoff in one 2x2 mm package.

ROHS3 compliant.

Frequently asked questions

What are the fault protections provided by BQ24311DSGT?

The BQ24311DSGT provides overcurrent, overtemperature, overvoltage, and undervoltage protection for a single-cell lithium-ion battery. These four protections cover short-circuit, thermal runaway, charger overvoltage, and deep-discharge prevention in one IC.

What is the BQ24311DSGT used for?

The BQ24311DSGT is a battery protection IC for single-cell lithium-ion packs. It's used as a front-end protector between the charger input and the cell in portable electronics, handheld instruments, industrial battery-powered devices, and automotive-grade systems where the -40°C to 125°C temperature range is required.
