A programmable timer controls the charge termination — no I²C or SMBus interface needed, making it a straightforward drop-in for portable equipment where a simple hardware-timed charge cycle is sufficient. ## Fault protection set — over-temp, over-voltage, short-circuit On-chip fault protection covers over-temperature, over-voltage, and output short-circuit conditions — no external supervisory IC required for basic Li-ion safety compliance in consumer and industrial portable designs. The junction temperature rating spans 0°C to 125°C, allowing the charger IC to sit near the battery or inside a sealed enclosure without derating the charge current at moderate ambient temperatures. ## VSON-10 exposed-pad package and supply rail Maximum supply voltage is 6.5V; the input rail can be a 5V USB bus or a 5V wall adapter without a separate pre-regulator. Base product number BQ24085 — the DRCR suffix is the VSON-10 reel variant; the same die is available in other package options for design flexibility.","metaTitle":"BQ24085DRCR Texas Instruments Li-Ion Charger, 750mA, VSON-10","metaDescription":"BQ24085DRCR single-cell Li-Ion/Polymer charger IC, 750mA max charge current, over-temp/over-voltage/short-circuit protection, 0-125°C TJ, VSON-10.","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":"10-VFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24085","Battery Pack Voltage":"4.2V","Charge Current - Max":"750mA","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-VSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48f8bde0f5fbcfa4ef1a45a0a7627fe5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24085DRCR?","answer":"The maximum programmable charge current is 750mA — set by an external resistor from the ISET pin to ground.
