The undervoltage lockout disconnects the cell when its voltage drops below the safe cutoff, protecting against deep discharge that can permanently damage a Li-ion cell. Overvoltage protection disconnects charging when the cell voltage rises above the regulation limit, a safeguard against charger runaway. Short-circuit detection is a faster, higher-threshold trip that responds to a dead-short on the pack terminals. ## Lifecycle and sourcing posture It is RoHS3 compliant.","metaTitle":"BQ29732DSET Battery Protection IC, 1-Cell Li-Ion, 6-WSON","metaDescription":"TI BQ29732DSET single-cell Li-Ion/Polymer battery protection IC with overcurrent, over/under voltage, and short-circuit protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Protection","Mounting Type":"Surface Mount","Package / Case":"6-WFDFN","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over/Under Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-WSON (1.5x1.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.25000","currency":"USD"},{"qty":10,"price":"$1.11900","currency":"USD"},{"qty":25,"price":"$1.06240","currency":"USD"},{"qty":100,"price":"$0.87280","currency":"USD"},{"qty":250,"price":"$0.81588","currency":"USD"},{"qty":500,"price":"$0.72102","currency":"USD"},{"qty":1250,"price":"$0.56922","currency":"USD"},{"qty":2500,"price":"$0.53700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b222c915dfe6db86cde422f696c81d8f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the protection features of BQ29732DSET?","answer":"The BQ29732DSET integrates overcurrent, overvoltage, undervoltage, and short-circuit protection for a single Li-ion or Li-polymer cell."},{"question":"Is BQ29732DSET suitable for 3.7V Li-ion cells?","answer":"Yes, the BQ29732DSET is designed for single-cell lithium-ion and lithium-polymer batteries, which have a nominal voltage of 3.6 V to 3.7 V and a full-charge voltage of 4.2 V.
