It delivers a programmable charge current up to 500 mA, set by an external resistor — the actual charge rate is a function of the resistor value and the thermal budget of the 10-VSON package. Input supply is rated to 6.5 V max, making it suitable for USB ports or regulated wall adapters. The IC integrates over-temperature fault protection, so a thermal event shuts down the charger without external sensing components. ## Programmable current and timer with USB interface Charge current and a safety timer are programmable via external components — the current set resistor and a timing capacitor define the fast-charge rate and the total charge duration. The USB interface is the primary power input, but any 4.5 V to 6.5 V supply works. The battery regulation voltage is fixed at 4.2 V, matching standard single-cell Li-Ion and Li-Polymer termination voltage. For a 3.7 V nominal cell, the charger terminates at 4.2 V — that is the correct full-charge voltage for that chemistry. ## Active production — no EOL notice on record No end-of-life notification or successor part has been published. Sourcing is confirmed through the distribution channel — quoted to order against BOM quantity.","metaTitle":"BQ24027DRCR Li-Ion Charger IC – 500 mA, 10-VSON, Active","metaDescription":"Texas Instruments BQ24027DRCR single-cell Li-Ion/Polymer charger IC. 500 mA max charge current, USB interface, -40°C to 125°C junction temp.","metaKeywords":null},"attributes":{"series":"bqTINY™-II","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™-II","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"USB","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","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24027","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-VSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8700","priceTiers":[{"qty":1,"price":"$6.87000","currency":"USD"},{"qty":10,"price":"$6.16600","currency":"USD"},{"qty":25,"price":"$5.82880","currency":"USD"},{"qty":100,"price":"$5.05170","currency":"USD"},{"qty":250,"price":"$4.79268","currency":"USD"},{"qty":500,"price":"$4.30046","currency":"USD"},{"qty":1000,"price":"$3.66600","currency":"USD"},{"qty":3000,"price":"$3.66600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/675c51f48f898e813e2537c7b97306cf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24027DRCR/alternatives.json"},"ai":{"faq":[{"question":"What is the max charge current for BQ24027DRCR?","answer":"The maximum programmable charge current is 500 mA.
