For a typical 1000 mAh cell, that is roughly a 0.5C rate — expect a full charge cycle in about 2.5 to 3 hours from a depleted state, assuming the thermal pad keeps the junction below the thermal regulation threshold. The charge current is constant and programmable, so the BOM resistor sets the rate; the 500 mA limit is the maximum, not the default. The USB interface means the charger accepts 5V from a USB host, wall adapter, or power bank without needing a separate DC-DC converter or LDO ahead of it. The 6.5V max supply gives enough headroom for a 5V rail with tolerance, but the dropout between 5V input and 4.2V battery is only 0.8V — the linear regulator in the charger stays in regulation as long as the input stays above ~4.4V. ## 20-VQFN package — thermal and layout notes The 20-VFQFN with exposed pad (3.5x4.5 mm) is the thermal path for a linear charger.","metaTitle":"BQ25015RHLR USB Li-Ion Charger IC, 500 mA, 20-VQFN","metaDescription":"Texas Instruments BQ25015RHLR single-cell Li-Ion/Polymer charger IC with USB interface, 500 mA max charge current, -40°C to 125°C range.","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":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25015","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2170","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/51c80f912ef1a2cd6fb5012479104348.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25015RHLR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25015RHLR support USB charging?","answer":"Yes, the charger includes a USB interface, meaning it can be powered directly from a USB port or a regulated 5V supply without additional components."},{"question":"Is BQ25015RHLR compatible with 4.2V batteries?","answer":"Yes, the battery pack voltage is specified as 4.2V, which is the standard termination voltage for single-cell Li-Ion and Li-Polymer cells."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25015RHLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25015RHLR when reusing this data.
