Its 500 mA max charge current sets the charge-rate ceiling for the battery. The USB interface means the part can draw power directly from a USB host or wall adapter without an external DC-DC stage — the 6.5 V supply max covers the 5 V USB bus with margin. ## Programmable features and protection Charge current and charge timer are programmable via external components, giving the designer control over the charge profile without an I2C bus. The constant-current constant-voltage algorithm terminates at 4.2 V battery pack voltage. Fault protection includes over-temperature shutdown, and the junction is rated to 125°C — useful when the charger sits near a processor or power amplifier in a sealed enclosure. ## Package and footprint Housed in a 20-VFQFN exposed-pad package (3.5x4.5 mm body), the part requires a thermal pad on the PCB to dissipate heat from the linear pass element.","metaTitle":"BQ25012RHLR Texas Instruments 1-Cell Li-Ion Charger, USB","metaDescription":"BQ25012RHLR from Texas Instruments is a 1-cell Li-Ion/Polymer linear charger with USB interface, 500 mA max charge current, and -40°C to 125°C 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":"USB","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","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25012","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":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9860","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2f68bb40b7e42ea52bfccc5e91546cc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ25012RHLR support USB input?","answer":"Yes, the interface is USB.
