It communicates over a single-wire HDQ interface, keeping the pin count low on a 10-VSON (3x4 mm) package. ## 10-VSON exposed-pad — layout and thermal path The 10-VFDFN exposed pad (10-VSON) package requires a thermal land pattern on the PCB that matches the pad dimensions for heat sinking. The exposed paddle is the primary thermal path for the monitor during high-rate charge/discharge cycles. The 3x4 mm footprint fits tight battery-pack layouts. ## Temperature grade — consumer portable gear It is not specified for automotive under-hood or industrial extended-temperature environments.","metaTitle":"BQ27000DRKRG4 Battery Monitor, HDQ Interface, 10-VSON","metaDescription":"Texas Instruments BQ27000DRKRG4 single-cell Li-ion battery monitor with HDQ interface in 10-VSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqJUNIOR™","Package":"Tape & Reel (TR)","Function":"Battery Monitor","Interface":"HDQ","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion/Polymer","Base Product Number":"BQ27000","Operating Temperature":"-20°C~70°C(TA)","Supplier Device Package":"10-VSON (3x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/999bcb6add1170e218288b594939e324.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BQ27000DRKR and BQ27000DRKRG4?","answer":"The suffix G4 typically indicates a lead-free (RoHS-compliant) finish compared to an earlier non-G4 variant.
