The USB interface allows direct connection to a 5 V bus; the 16 V max supply provides headroom for adapter inputs without external clamp circuitry. Fault protection includes over-temperature, reverse-current, and short-circuit detection — these are integrated, not external add-ons, which simplifies the BOM for a portable or handheld product. ## 1.5 A charge current and programmable timer — thermal design note Charge current is constant and programmable via an external resistor; the 1.5 A max sets the upper bound for the thermal budget. The programmable timer terminates charging after a set interval, providing a safety backup if the battery never reaches the 4.2 V full-charge threshold. ## Active lifecycle — no obsolescence concern for new designs For volume BOM planning, the part is sourced per RFQ through our distribution channel; current pricing and lead time are confirmed at quote time. ## 20-VQFN package — footprint and rework considerations Surface-mount assembly follows standard QFN reflow profiles.","metaTitle":"BQ24032ARHLRG4 Texas Instruments Li-Ion Charger IC – Active","metaDescription":"BQ24032ARHLRG4 from TI bqTINY III series: single-cell Li-Ion/Polymer charger, 1.5A max, USB interface, -40°C to 125°C, 20-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™ III","Package":"Tape & Reel (TR)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24032","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ac9036052305c74527f033a709990eb1.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24032ARHLRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24032ARHLRG4 when reusing this data.
