It integrates over-current, over-voltage, and short-circuit fault protection, and operates from a supply up to 24 V. ## Cell count and chemistry flexibility Supporting 1 to 4 series cells, this charger covers the most common battery pack configurations for portable devices — from single-cell phones and tablets to 4-cell notebook packs. The multi-chemistry capability means it works with Li-ion, Li-polymer, and other rechargeable chemistries, so a single BOM line can serve different pack types across a product family. ## SMBus communication for smart charging The SMBus interface allows the system host to set charge current, voltage, and termination thresholds dynamically, and to read back battery status. This is the standard protocol for smart batteries (Smart Battery Data Specification), so the BQ24780SRUYT integrates directly into an existing SMBus-compatible power management scheme without additional glue logic. ## Protection and package Built-in fault protection for over-current, over-voltage, and short circuit reduces external component count and simplifies safety certification. Surface-mount assembly keeps the board profile low.","metaTitle":"BQ24780SRUYT Battery Charger IC, Multi-Chemistry, 1-4 Cells","metaDescription":"TI BQ24780SRUYT multi-chemistry battery charger IC for 1-4 cells, SMBus interface, fault protection, -40°C to 85°C, 28-WQFN.","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)","Interface":"SMBus","Mounting Type":"Surface Mount","Package / Case":"28-WFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage, Short Circuit","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ24780","Battery Pack Voltage":"-","Charge Current - Max":"-","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"28-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8900","priceTiers":[{"qty":1,"price":"$3.89000","currency":"USD"},{"qty":10,"price":"$3.49700","currency":"USD"},{"qty":25,"price":"$3.30560","currency":"USD"},{"qty":100,"price":"$2.86490","currency":"USD"},{"qty":250,"price":"$2.71796","currency":"USD"},{"qty":500,"price":"$2.43880","currency":"USD"},{"qty":1250,"price":"$2.07900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/86e443556c3c6a788d7a91c142aa5866.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24780SRUYT/alternatives.json"},"ai":{"faq":[{"question":"How many cells can BQ24780SRUYT charge?","answer":"The BQ24780SRUYT charges 1 to 4 series cells, covering single-cell through 4-cell battery packs."},{"question":"Is BQ24780SRUYT RoHS compliant?","answer":"Yes, the BQ24780SRUYT is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24780SRUYT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24780SRUYT when reusing this data.
