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.
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.
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.
