It integrates the protection FETs and sense resistor internally, so the external BOM stays minimal — useful when board area is tight and the protection decision needs to be self-contained rather than delegated to a gauge or fuel-gauge companion. The 8-WSON (2x2 mm) package fits into the edge of a battery pack PCB or a handheld device's power management section. No last-time-buy window has been announced, and no successor has been designated. For a protection IC that is often qualified into a battery pack assembly with a multi-year product life, active status removes one sourcing risk variable. The part is ROHS3 compliant. ## What the protection set means for the BOM The fault protection block covers overcurrent, overtemperature, overvoltage, undervoltage, and short circuit — five conditions in one IC. That is the full set a single-cell Li-ion pack needs per the typical safety guidelines, without adding a separate overvoltage protector or a PTC fuse. The internal FETs handle the disconnect, so the series-pass element is already on-chip. The designer only needs to size the input capacitor and ensure the PCB trace width supports the pack's discharge current.","metaTitle":"BQ24382DSGT Texas Instruments Battery Protection IC, Active","metaDescription":"Texas Instruments BQ24382DSGT Li-ion battery protection IC with over/under voltage, overcurrent, overtemperature, short circuit protection. -40°C to 125°C.","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, Short Circuit","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ24382","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.86600","currency":"USD"},{"qty":25,"price":"$0.82200","currency":"USD"},{"qty":100,"price":"$0.67530","currency":"USD"},{"qty":250,"price":"$0.63128","currency":"USD"},{"qty":500,"price":"$0.55788","currency":"USD"},{"qty":1250,"price":"$0.44043","currency":"USD"},{"qty":2500,"price":"$0.41550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8b7b3145207e0172176764125e714807.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24382DSGT/alternatives.json"},"ai":{"faq":[{"question":"What is the BQ24382DSGT's function and what does it protect against?","answer":"It is a Li-ion battery protection IC.
