The charge current is programmable up to 1 A, which sets the charge-time floor for a typical 1000 mAh to 2000 mAh cell — expect roughly a 1-to-2 hour charge from a depleted state, depending on the programmed current and the thermal management of the PCB. The input supply range extends to 6.45 V max, so the part can tolerate the 5 V nominal from a USB host or adapter with margin for cable drop and transient overvoltage. ## Fault protection set — no external supervisor needed On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions. This means the charger can be used in a portable design without a separate battery-protection IC for these three fault types, saving board area and BOM cost. The protection is active during both charging and standby. ## Package and footprint — 10-HVSSOP with thermal pad The HVSSOP variant includes an exposed thermal pad on the underside — the PCB layout must include a corresponding copper land and via array to the ground plane to keep the junction temperature within limits at 1 A charge current.","metaTitle":"BQ24091DGQR USB Li-Ion Charger, 1A, 10-HVSSOP","metaDescription":"Texas Instruments BQ24091DGQR single-cell Li-Ion/Polymer charger with USB interface, programmable 1A max charge current, over-temp/over-voltage/short-circuit","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Series":"-","Interface":"USB","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"10-PowerTFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24091","Battery Pack Voltage":"4.2V","Charge Current - Max":"1A","Operating Temperature":"0°C ~ 125°C (TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"6.45V","Supplier Device Package":"10-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdee6fb711b7ffa38d45fa435662349c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24091DGQR have built-in power path management?","answer":"The evidence does not list power path management as a feature.
