The constant-current phase is set by a single resistor to ground; the timer terminates charging if the battery does not reach the 4.2 V full-charge threshold within the programmed window. Fault protection is built in: over-temperature, reverse current, and short-circuit protection are on-chip, eliminating the need for external supervisory components in most single-cell portable designs. ## Package and thermal — layout checklist The 20-VFQFN with exposed pad (3.5x4.5 mm) requires a thermal land pattern on the PCB with multiple vias to the ground plane. The exposed paddle is the primary heat path; without adequate copper area the 1.5 A charge current will push the die above the 125°C junction limit in ambient above 50°C.","metaTitle":"BQ24030RHLRG4 Li-Ion Battery Charger IC, 1.5 A Max, USB","metaDescription":"TI BQ24030RHLRG4 single-cell Li-Ion/Polymer charger IC, 1.5 A max charge current, USB interface, 16 V input, -40°C to 125°C, 20-VQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™ III","Package":"Tape & Reel (TR)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24030","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ac9036052305c74527f033a709990eb1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current and USB input voltage for BQ24030?","answer":"The maximum charge current is 1.5 A, programmable via an external resistor.
