Its headline rating is the 8.064A programmable charge current, which sets the external MOSFET and inductor sizing for the buck converter stage. The constant-current, constant-voltage profile is configured over the I²C interface, so the host MCU must have an available I²C port and firmware to handle the SMBus-like protocol. ## Obsolete — plan your BOM around surplus or last-time-buy stock Texas Instruments lists the BQ24747RHDR as Obsolete. For new designs, look at current-generation SMBus/I²C chargers in the BQ247xx family — but the pinout and register map will differ. Confirm date code and moisture sensitivity before using a reel. ## Package and mounting — 28-VQFN with exposed pad The BQ24747RHDR comes in a 28-VFQFN Exposed Pad package, supplier device package 28-VQFN (5x5). Mounting is surface mount, supplied in Tape & Reel. ## Temperature grade and fault protection The IC includes over-voltage fault protection on the battery and input rails. Supply voltage maximum is 24V, so a 2-cell to 4-cell pack stays within the input range.","metaTitle":"BQ24747RHDR Battery Charger IC, I²C, 8.064A Max, Obsolete","metaDescription":"Texas Instruments BQ24747RHDR multi-chemistry battery charger, I²C interface, 8.064A max charge current, 2-4 cells, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"28-VFQFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"2 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24747","Battery Pack Voltage":"19.2V (Max)","Charge Current - Max":"8.064A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"28-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fa24b7ca06559f462d31492b2f2663d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24747RHDR require I²C programming?","answer":"Yes, the charge current, voltage, and other parameters are configured over the I²C interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24747RHDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24747RHDR when reusing this data.
