It delivers up to 3 A constant charge current from a supply up to 24 V, with programmable current and voltage setpoints via the I²C bus. Integrated fault protection covers over-current and over-voltage conditions, reducing external component count for the protection circuit. ## Charge current and cell count range Maximum charge current is 3 A, which sets the charging time floor for a given battery capacity. The 1- to 4-cell support means the charger can handle battery pack voltages up to 18.8 V — suitable for power tools, portable medical gear, or industrial handhelds with series-cell stacks. ## Active production and package details","metaTitle":"BQ25672RQMR I²C Controlled 1-4 Cell 3A Li-Ion Charger PMIC","metaDescription":"Texas Instruments BQ25672RQMR: I²C-controlled 1- to 4-cell Li-Ion/Polymer charger, 3 A max charge current, 24 V supply max, 29-VFQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"29-VFQFN","Product Status":"Active","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ25672","Battery Pack Voltage":"18.8V (Max)","Charge Current - Max":"3A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Voltage","Voltage - Supply (Max)":"24V","Supplier Device Package":"29-VQFN-HR (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2800","priceTiers":[{"qty":1,"price":"$4.28000","currency":"USD"},{"qty":10,"price":"$3.84600","currency":"USD"},{"qty":25,"price":"$3.63600","currency":"USD"},{"qty":100,"price":"$3.15120","currency":"USD"},{"qty":250,"price":"$2.98960","currency":"USD"},{"qty":500,"price":"$2.68256","currency":"USD"},{"qty":1000,"price":"$2.26240","currency":"USD"},{"qty":3000,"price":"$2.14928","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/46a7593edd008f1d79b2f3e44a2542f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25672RQMR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25672RQMR support I²C charge current control?","answer":"Yes, the charger uses an I²C interface for programming charge current and voltage setpoints."},{"question":"What is the lead time for BQ25672RQMR?","answer":"Lead time is confirmed at quote time based on current factory backlog and distributor inventory.
