The input supply range extends to 16V, so it can run from a 5V USB port, a 12V wall adapter, or an unregulated 15V rail without needing an external pre-regulator. The programmable features include charge current and a safety timer, giving the designer control over charge profile and termination. ## 2A charge current and thermal design in a 20-VFQFN The 2A maximum charge current is the headline rating for this part. The exposed pad is the primary heat path — the PCB copper area directly under it sets the effective thermal resistance. Built-in over-voltage and over-temperature protection reduce external component count.","metaTitle":"BQ24108RHLRG4 bqSWITCHER Li-Ion Charger, 2A, 16V Input","metaDescription":"Texas Instruments BQ24108RHLRG4 single-cell Li-Ion/Polymer charger, 2A max charge current, 16V input, over-voltage protection, -40°C to 85°C, 20-VFQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqSWITCHER™","Package":"Tape & Reel (TR)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24108","Battery Pack Voltage":"4.2V","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c4c919ecd042ba26e7e80ee114720c9b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the BQ24108RHLRG4 charging current?","answer":"The maximum charge current is 2A, programmable via an external resistor.
