It communicates over an I²C interface, allowing the host to verify the pack's authenticity before enabling charge or discharge. Housed in a 20-TSSOP package (4.40 mm width), the BQ27350PWRG4 is a surface-mount component suited for reflow assembly. The 0.65 mm pin pitch on the TSSOP body is a standard footprint that routes out on two-layer boards without via-in-pad. The supplier device package is listed as 20-TSSOP, matching the package/case specification. Tape & Reel (TR) packaging supports automated pick-and-place for volume production. ## Active lifecycle and sourcing The base product number is BQ27350, so variant suffixes (PWRG4) indicate packaging and environmental grade.","metaTitle":"BQ27350PWRG4 Texas Instruments Battery Authenticator","metaDescription":"BQ27350PWRG4 Texas Instruments Impedance Track battery authentication IC, 1-cell Li-Ion/Polymer, I2C, -40 to 85C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Impedance Track™","Package":"Tape & Reel (TR)","Function":"Battery Authentication","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion/Polymer","Base Product Number":"BQ27350","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/84c596882a93522808e5af4f2d32c9b5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ27350PWRG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27350PWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27350PWRG4 when reusing this data.
