The 10.2 V supply maximum means it can run from a 5 V USB rail or a 9 V wall adapter without a pre-regulator — the internal pass transistor drops the difference as heat, so the thermal budget at 1 A charge current demands good PCB copper area under the exposed pad. ## Package and thermal path Housed in a 10-WFDFN with exposed pad (3 mm x 2 mm), the part relies on the pad soldered to a PCB copper plane to pull heat out of the die — at 1 A charge current from a 5 V input, the pass transistor dissipates roughly 0.8 W, and the junction-to-ambient thermal resistance depends on the board's copper area, not just the package. ## Protection and lifecycle status On-chip fault protection covers over-temperature and over-voltage conditions — the charger halts the cycle if the die exceeds the thermal limit or the input voltage spikes above the safe threshold.","metaTitle":"Texas Instruments BQ25050DQCT Li-Ion Charger, 1A, 10WSON","metaDescription":"Texas Instruments BQ25050DQCT single-cell Li-Ion linear charger, 1A max charge current, 10.2V supply max, 10-WFDFN exposed pad package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"10-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25050","Battery Pack Voltage":"4.2V","Charge Current - Max":"1A","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"10.2V","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0800","priceTiers":[{"qty":1,"price":"$2.08000","currency":"USD"},{"qty":10,"price":"$1.86800","currency":"USD"},{"qty":25,"price":"$1.76240","currency":"USD"},{"qty":100,"price":"$1.50140","currency":"USD"},{"qty":250,"price":"$1.40980","currency":"USD"},{"qty":500,"price":"$1.23358","currency":"USD"},{"qty":1250,"price":"$1.02210","currency":"USD"},{"qty":2500,"price":"$0.99750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/86715420b1789c110d336d71dd01d999.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25050DQCT/alternatives.json"},"ai":{"faq":[{"question":"What is the charge current of BQ25050DQCT?","answer":"The maximum programmable charge current is 1 A, set by an external resistor.
