It handles a maximum battery pack voltage of 19.2 V and accepts a supply up to 24 V. The charging current is constant and programmable via the bus. ## Fault protection and package On-chip fault protection covers over-current, over-voltage, and short-circuit conditions, reducing the need for external supervisory circuitry. ## Obsolete — sourced to order TI lists the BQ24726RGRT as obsolete.","metaTitle":"BQ24726RGRT Li-Ion Battery Charger, I²C, 1-4 Cells, Obsolete","metaDescription":"Texas Instruments BQ24726RGRT SMBus/I²C battery charger for 1-4 Li-ion cells, max 19.2V pack voltage, 24V input.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Obsolete","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":"$4.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d34e771aa1952b9f8f864f6de8fe2d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ24726RGRT charge a 4-cell lithium battery?","answer":"Yes. The BQ24726RGRT supports 1 to 4 series Li-ion cells, with a maximum battery pack voltage of 19.2 V. A 4-cell pack at 4.2 V per cell (16.8 V nominal) is well within its range."},{"question":"What is the difference between BQ24726RGRT and BQ24725RGRT?","answer":"Both are SMBus/I²C Li-ion chargers in similar VQFN packages. The BQ24726 supports a higher maximum battery pack voltage (19.2 V vs 18.04 V for the BQ24725), which makes it the better fit for 4-cell designs.
