It communicates over an I²C interface and comes in a 10-VSON (3x4) package with an exposed thermal pad. This part monitors one cell only — if you are sizing for a 2-series stack, this is not the right monitor. The I²C bus lets a host MCU read voltage, temperature, and remaining capacity without an extra ADC channel. ## NRND — plan the last-time buy now That means TI is not actively promoting it for new projects, and a last-time-buy window is the typical next step. If you have this on a current BOM, secure your bridge quantity and start qualifying a replacement. A pin-compatible second source is not documented either — the replacement path will require a layout review and firmware port. ## Temperature grade and package rework Operating temperature spans -20°C to 70°C — a commercial-grade range that suits portable consumer devices, handheld instruments, and indoor battery-bank monitoring. Not rated for automotive or industrial enclosures where ambient exceeds 70°C. Rework is manageable with a hot-air station if the pad is properly tinned — the part is small enough that the pad wets quickly, but the 0.5 mm pitch demands a steady hand and a fine tip for alignment.","metaTitle":"BQ27000DRKR Battery Monitor, bqJUNIOR, I²C, 1-Cell Li-Ion","metaDescription":"Texas Instruments BQ27000DRKR single-cell Li-Ion/Polymer battery monitor with I²C interface.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqJUNIOR™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Monitor","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Not For New Designs","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":"$4.3035","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/999bcb6add1170e218288b594939e324.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use BQ27000DRKR with a 2-cell Li-ion battery?","answer":"No — the BQ27000DRKR is a single-cell monitor. It is rated for one cell only. For a 2-series pack you need a multi-cell gauge like the BQ28Z610 or similar."},{"question":"Is BQ27000DRKR compatible with 5V I²C?","answer":"The part is a 1-cell Li-Ion monitor with an I²C interface. The I²C pins are powered from the battery voltage (typically 2.5–4.5 V for a single cell). 5V I²C logic is outside the normal operating range of the battery voltage; level shifting or a different gauge is required for a 5V bus."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27000DRKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27000DRKR when reusing this data.
