An I²C interface allows the host microcontroller to program charge current and voltage, making it suitable for multi-chemistry or multi-cell systems where the charging profile must be adjusted dynamically. Integrated fault protection covers over-current, over-voltage, and short-circuit conditions, reducing external component count and simplifying the safety design.","metaTitle":"BQ24726RGRR Li-Ion Battery Charger IC, I²C, 1–4 Cells","metaDescription":"TI BQ24726RGRR Li-Ion battery charger IC with I²C interface, 1–4 cells, 19.2V max pack voltage, fault protection, 0°C–125°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24726","Battery Pack Voltage":"19.2V (Max)","Charge Current - Max":"-","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"20-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d34e771aa1952b9f8f864f6de8fe2d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many cells can BQ24726RGRR charge?","answer":"The BQ24726RGRR supports charging 1 to 4 series Li-Ion cells, with a maximum battery pack voltage of 19.2V."},{"question":"What fault protections does BQ24726RGRR have?","answer":"The BQ24726RGRR integrates over-current, over-voltage, and short-circuit protection, eliminating the need for external comparators or supervisory circuits."},{"question":"What is the difference between BQ24726RGRR and BQ24725?","answer":"The BQ24726 is a pin-compatible variant within the same family; the primary difference lies in the I²C register map and charge voltage set-point resolution. For exact register differences, refer to the respective datasheets.
