The 1.5 A maximum charge current sets the charge-time floor for a typical 1000 mAh to 2000 mAh cell — expect a full charge in roughly one to two hours at the constant-current stage. The IC integrates a pass transistor and current-sense resistor, so the external BOM stays lean: just a few capacitors and the programming resistor for the charge current. ## Protection set and programmable features Fault protection covers over-temperature, over-voltage, reverse current, and short circuit — four conditions that cover the common failure modes in a single-cell charging path. The over-voltage protection clamps the battery voltage at 4.2 V, matching the standard Li-Ion termination voltage. The reverse-current block prevents the battery from back-driving the input when the supply is removed. Programmable features include the charge current and a safety timer, both set with external resistors. The timer provides a backup termination in case the battery never reaches the 4.2 V threshold — useful for deeply discharged cells. The part comes in a 16-VFQFN exposed pad package, 3 mm × 3 mm body (supplier device package 16-VQFN). Supply voltage max is 6.4 V, which covers USB VBUS (5 V nominal) with margin for cable drop and transient overshoot.","metaTitle":"BQ24072TRGTR Li-Ion Charger IC, 1.5 A Max, USB Interface","metaDescription":"Texas Instruments BQ24072TRGTR single-cell Li-Ion charger IC with 1.5 A max charge current, USB interface, and over-temperature/voltage protection.","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":"USB","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24072","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.4V","Supplier Device Package":"16-VQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c24e698e49b346e7fded4bc69cd35d5a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24072TRGTR?","answer":"The maximum charge current is 1.5 A, set by an external programming resistor.
