It delivers a programmable constant charge current up to 1.5 A max, sourced from a supply rail that can go as high as 16 V — covering USB 5 V, 9 V, and 12 V wall adapters without a separate input regulator. The part integrates over-temperature, reverse-current, and short-circuit fault protection, so the BOM does not need a separate supervisor or protection FET for basic charging duty. ## Package and mounting At 1.5 A the power dissipation in a linear charger is the voltage drop across the pass element times the current. If the input is 5 V and the battery is at 3.7 V, the drop is 1.3 V × 1.5 A ≈ 2 W — that heat has to go into the PCB copper through the 20-VQFN exposed pad. The 16 V max supply means this charger can sit on a 12 V automotive rail or a 12 V wall wart, but not on a 24 V industrial bus — that would exceed the abs-max and pop the part. For 24 V systems you step down first or pick a different charger family. No last-time-buy notice, no end-of-life window.","metaTitle":"BQ24070RHLR Li-Ion Charger IC, 1.5 A, 16 V Input, 20-VQFN","metaDescription":"Texas Instruments BQ24070RHLR single-cell Li-Ion/Polymer charger IC. 1.5 A max charge current, 16 V max supply, -40 to 125 °C junction 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":"-","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":"BQ24070","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":"$3.2600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c3b1c9df67e6436593e1be71a1cae38e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24070RHLR compatible with 2S battery packs?","answer":"No — this part is designed for single-cell (1S) packs only, with a battery regulation voltage of 4.2 V.
