It uses an I²C interface to set balancing thresholds and report fault conditions — overvoltage, overcurrent, and overtemperature are all handled on-chip. The 2-cell limit is non-negotiable: this part balances exactly two series lithium-ion cells. For a single-cell pack you would need a different balancer or a monitor like the BQ79612PAPRQ1, which handles one cell but adds SPI/UART and AEC-Q100 qualification. For 3–4 cells the older BQ2084DBT-V143 uses SMBus and covers 2 to 4 cells, but its temperature range stops at 85°C and it comes in a tube package. The I²C interface lets a host microcontroller read fault status and adjust the balancing current or voltage thresholds on the fly — useful if the pack chemistry or aging profile changes over the product lifetime. ## Active production — no lifecycle concern For current BOMs, there is no pressure to last-time-buy or find a drop-in replacement. Confirm the 24-VQFN (4x4) footprint and the I²C bus voltage level before committing the layout.","metaTitle":"BQ25887RGET – TI 2-Cell Li-Ion Battery Balancer, I²C","metaDescription":"Texas Instruments BQ25887RGET active-production 2-cell lithium-ion battery balancer with I²C control, overvoltage/overcurrent/overtemperature protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Balancer","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"2","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ25887","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9000","priceTiers":[{"qty":1,"price":"$6.90000","currency":"USD"},{"qty":10,"price":"$6.20100","currency":"USD"},{"qty":25,"price":"$5.86240","currency":"USD"},{"qty":100,"price":"$5.08070","currency":"USD"},{"qty":250,"price":"$4.82012","currency":"USD"},{"qty":500,"price":"$4.32510","currency":"USD"},{"qty":1250,"price":"$3.68700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f83bc825d9b608f106d6a9755d8800f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25887RGET/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25887RGET support overvoltage and overcurrent protection?","answer":"Yes.
