Its maximum charge current of 1.5A is programmable via an external resistor, letting you match the charge rate to the battery capacity — a 1500 mAh cell charges at 1C, while a 750 mAh cell would need a lower set-point to stay within the cell's safe charge rate. ## Protection suite — what keeps the cell safe Four fault-protection blocks are integrated: over-temperature, over-voltage, reverse current, and short circuit. The over-temperature protection monitors die temperature and throttles or shuts down the charger before the junction exceeds the 125°C rating — critical when charging at 1.5A in a compact 3x3 mm QFN package with limited board copper to sink heat. The 4.2V battery pack voltage is the standard termination for lithium-ion cells. The charger enters constant-voltage mode once the cell reaches this threshold, then tapers the current until the safety timer expires or the termination current threshold is met. ## Supply rail and USB compatibility Maximum supply voltage is 6.4V, which covers USB VBUS (5V nominal) with margin for cable drop and transient overshoot. The USB interface designation means the charger can negotiate current limits per the USB specification, though the exact enumeration protocol depends on the upstream host or dedicated charging port. ## Package and thermal design The 16-VFQFN with exposed pad (supplier device package 16-VQFN 3x3 mm) requires a thermal land pattern on the PCB to conduct heat away from the die. Surface mount only. ## Lifecycle and supply posture For current designs this means no forced requalification risk.","metaTitle":"BQ24075TRGTR USB Li-Ion Charger IC, 1.5A Max, 16-VQFN","metaDescription":"Texas Instruments BQ24075TRGTR single-cell Li-Ion battery charger with USB interface, 1.5A programmable charge current, 4.2V termination, fault 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":"BQ24075","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":"$2.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c24e698e49b346e7fded4bc69cd35d5a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24075TRGTR?","answer":"The actual charge current is set below this maximum by the resistor value chosen."},{"question":"Is BQ24075TRGTR compatible with 4.2V lithium-ion batteries?","answer":"Yes.
