It sits in the Automotive, AEC-Q100, Functional Safety (FuSa) series, so the qualification baseline includes the reliability screening and safety-process documentation expected for production battery-management systems in hybrid/electric vehicles, industrial energy storage, and heavy equipment. On-chip over/under-voltage fault protection means the controller can trigger a fault flag and alert the host without waiting for the next measurement cycle — useful for catching a cell that drifts outside the programmed window during charge or discharge. The operating temperature range of -40°C to 105°C covers under-hood automotive and outdoor industrial enclosures; the 80-TQFP (12x12 mm) package is a standard surface-mount footprint for mixed-signal controllers. ## Cell-count flexibility and UART interface Supporting 6 to 16 cells in a single device lets the BQ76PL455ATPFCTQ1 adapt to different battery-pack voltages without changing the controller IC. The UART interface keeps the communication wiring simple: a single serial line to the host MCU. ## Lifecycle and sourcing posture Listed as Active, so there is no last-time-buy clock running on this part. It remains a current-production choice for new BMS designs.","metaTitle":"TI BQ76PL455ATPFCTQ1 Battery Multi-Function Controller","metaDescription":"Texas Instruments BQ76PL455ATPFCTQ1 multi-function battery controller, AEC-Q100 qualified, supports 6-16 cells, UART interface, over/under voltage protection.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, Functional Safety (FuSa)","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100, Functional Safety (FuSa)","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Multi-Function Controller","Interface":"UART","Mounting Type":"Surface Mount","Package / Case":"80-TQFP","Number of Cells":"6 ~ 16","lifecycle_stage":"eol_hot","Fault Protection":"Over/Under Voltage","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"80-TQFP (12x12)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$23.15000","currency":"USD"},{"qty":10,"price":"$21.34900","currency":"USD"},{"qty":25,"price":"$20.38960","currency":"USD"},{"qty":100,"price":"$18.23070","currency":"USD"},{"qty":250,"price":"$17.39116","currency":"USD"},{"qty":500,"price":"$16.97250","currency":"USD"}]},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fbq76pl455a-q1","sourceUrl":null},"ai":{"faq":[{"question":"How many cells does BQ76PL455ATPFCTQ1 support?","answer":"It supports 6 to 16 series cells."},{"question":"Is BQ76PL455ATPFCTQ1 AEC-Q100 qualified?","answer":"Yes, it is part of the Automotive, AEC-Q100, Functional Safety (FuSa) series."},{"question":"Is there a replacement or equivalent for BQ76PL455ATPFCTQ1?","answer":"The BQ79612PAPRQ1 is a newer-generation automotive battery monitor from TI, but it monitors a single cell (vs 6-16 for this part) and adds SPI alongside UART.
