It integrates overcurrent, overtemperature, and over/under voltage detection — a single-chip safeguard that replaces discrete comparator-and-fuse circuits. ## What the fault protection covers Three fault domains are monitored: overcurrent (charge/discharge), overtemperature, and over/under voltage. The IC latches off the output when any threshold is exceeded, preventing cell damage and thermal runaway — no external sense resistor needed for the overcurrent function. Because the protection is self-contained, the BOM count stays low: the IC plus a few passives and the Li-ion cell itself. The 8-WSON (2x2 mm) package with exposed pad keeps the board footprint under 4 mm², which matters when the protection circuit shares space with the cell connector and fuel gauge. Sourced through independent distribution against an RFQ.","metaTitle":"TI BQ24313DSGR Li-ion Battery Protection IC, -40°C to 125°C","metaDescription":"Texas Instruments BQ24313DSGR battery protection IC for Li-ion packs.
