The charge current is constant and programmable via the I²C interface — you set the current level in firmware rather than swapping a sense resistor, which simplifies BOM changes across different pack capacities. Supply voltage goes up to 24 V, so it works from common 19 V laptop adapters or 24 V industrial rails. The integrated fault protection covers over-current, over-voltage, and short-circuit conditions, reducing the need for external supervisory circuitry. ## 20-VFQFN with exposed pad — layout checklist The package is a 20-VFQFN with an exposed pad, 3.5 x 3.5 mm body (supplier device package 20-VQFN). Surface-mount only. Store the reels dry; this QFN is moisture-sensitive and needs a bake before reflow if the seal is broken. That is a commercial-to-hot range — fine for consumer notebooks, docking stations, and indoor industrial chargers, but not rated for the -40°C cold start an automotive or outdoor telecom design would need.","metaTitle":"BQ24707RGRT – TI Li-Ion Battery Charger, I²C, 1-4 Cells","metaDescription":"Texas Instruments BQ24707RGRT Li-Ion battery charger controller, I²C interface, supports 1-4 cells up to 19.2V pack voltage.","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); Cut Tape (CT)","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":"BQ24707","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":"$8.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6dcb01ca47f9e08f45f9e3df78916656.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for the BQ24707RGRT?","answer":"The charge current is constant and programmable via I²C.
