It reports state-of-charge and voltage via an HDQ or I²C interface, making it a drop-in for portable devices that need accurate fuel gauging without a custom algorithm. ## Interface and temperature range Communication is handled through either HDQ or I²C — both common on MCU and PMIC buses — so the host-side integration is straightforward. ## Package and mounting Housed in a 15-bump DSBGA (15-UFBGA) package, surface-mount only. The 0.5 mm pitch and small footprint suit space-constrained PCB layouts, but the BGA requires a solder-paste stencil and reflow profile — not a hand-solder part.","metaTitle":"BQ27546YZFR-G1 Texas Instruments Battery Monitor","metaDescription":"TI BQ27546YZFR-G1 single-cell Li-ion battery monitor with Impedance Track™, HDQ and I²C interface, -40°C to 85°C, 15-DSBGA.","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); Cut Tape (CT)","Function":"Battery Monitor","Interface":"HDQ, I²C","Mounting Type":"Surface Mount","Package / Case":"15-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ27546","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"15-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7620","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eeca25cae02076fb4b09e49f070d8261.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What interface does BQ27546YZFR-G1 support?","answer":"It supports both HDQ and I²C interfaces for host communication."},{"question":"What is the difference between BQ27546YZFR-G1 and BQ27541?","answer":"Both are single-cell Li-ion battery monitors from TI, but the BQ27546 uses the Impedance Track™ algorithm for state-of-charge estimation, while the BQ27541 uses a different gauging method.
