It integrates overcurrent, overtemperature, and over/under voltage fault protection into an 8-WSON (2x2) package — no external comparator or reference needed. ## Fault coverage and what each trip protects Overcurrent protection catches load-side shorts before the cell sees sustained high current; overtemperature protection shuts down the FET if the pack ambient exceeds the die limit; over/under voltage protection keeps each series cell inside its safe window. Together they cover the three failure modes that turn a Li-Ion pack into a fire risk. The 8-WFDFN Exposed Pad package lets the die sink heat into the PCB copper — critical because the overtemperature trip relies on the junction temperature, not the ambient air. ## Sourcing posture and package availability","metaTitle":"BQ24314CDSGT – TI Li-Ion Battery Protection IC, 8-WSON","metaDescription":"Texas Instruments BQ24314CDSGT Li-Ion battery protection IC with overcurrent, overtemperature, over/under voltage fault protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Function":"Battery Protection","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over/Under Voltage","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ24314","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2000","priceTiers":[{"qty":1,"price":"$1.20000","currency":"USD"},{"qty":10,"price":"$1.07300","currency":"USD"},{"qty":25,"price":"$1.01800","currency":"USD"},{"qty":100,"price":"$0.83630","currency":"USD"},{"qty":250,"price":"$0.78176","currency":"USD"},{"qty":500,"price":"$0.69084","currency":"USD"},{"qty":1250,"price":"$0.54540","currency":"USD"},{"qty":2500,"price":"$0.50904","currency":"USD"},{"qty":6250,"price":"$0.48359","currency":"USD"},{"qty":12500,"price":"$0.46541","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/75809e96af949c7b6b7eef9146213671.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24314CDSGT/alternatives.json"},"ai":{"faq":[{"question":"What fault protection does the BQ24314CDSGT include?","answer":"Overcurrent, overtemperature, and over/under voltage.
