It accepts a USB input and delivers a programmable constant charge current up to 1.5 A, with the battery regulation voltage fixed at 4.2 V. The 16 V maximum supply voltage gives headroom for 5 V USB or higher-voltage wall adapters without an external pre-regulator. ## Charge current and thermal design The 1.5 A maximum charge current is programmable via an external resistor, letting you set the charge rate to match the battery capacity and thermal budget. ## Protection and programmable features Built-in fault protection covers over-temperature, reverse current, and short-circuit conditions — the charger shuts down or limits current automatically without external monitoring. The programmable timer sets a safety timeout for the charge cycle, and the current-programming resistor also sets the termination threshold. These features reduce the external component count to a few resistors and capacitors around the 20-VFQFN package.","metaTitle":"BQ24035RHLR Texas Instruments bqTINY III Li-Ion Charger","metaDescription":"Texas Instruments BQ24035RHLR single-cell Li-Ion/Li-Po linear charger, 1.5 A max charge current, USB interface, 16 V input, -40 to 125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™ III","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":"Over Temperature, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24035","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4945","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ac9036052305c74527f033a709990eb1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24035RHLR?","answer":"The maximum charge current is 1.5 A, programmable via an external resistor. The actual current set in the design should account for the thermal dissipation in the linear pass element at the chosen input voltage."},{"question":"Is BQ24035RHLR compatible with 2-cell batteries?","answer":"No. The BQ24035RHLR is designed for single-cell (1-cell) Lithium-Ion or Lithium-Polymer batteries only, with a fixed 4.2 V battery regulation voltage. It cannot charge a 2-cell pack."},{"question":"Can BQ24035RHLR replace BQ24035RHLT?","answer":"The BQ24035RHLR and BQ24035RHLT share the same base product number BQ24035 and the same electrical specifications. The difference is in the packaging and reel options — the RHLR suffix indicates Tape & Reel packaging, while the RHLT suffix indicates a different reel or cut-tape variant. They are functionally interchangeable, but verify the reel quantity and packaging format for your assembly line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24035RHLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24035RHLR when reusing this data.
