The programmable timer gives a safety timeout if the battery never reaches the 4.2 V termination voltage. Fault protection covers over-temperature, over-voltage, reverse-current, and short-circuit — four separate monitors that each can shut down the charger independently. If you are comparing against a charger that lacks reverse-current protection, the BQ24075RGTT blocks battery discharge back into the USB port when the bus is unpowered — that matters for designs where the battery stays connected while the charger input floats. ## Lifecycle, compliance, and sourcing posture No end-of-life notice or PCN on the public record. The base product number BQ24075 covers a family of pin-compatible variants with different charge voltages and timer options — if your BOM calls for the RGTT suffix (VQFN-16, tape-and-reel), confirm the exact charge voltage and timer settings match the original design.","metaTitle":"BQ24075RGTT Li-Ion Charger IC – 1.5 A, USB, Active","metaDescription":"Texas Instruments BQ24075RGTT single-cell Li-Ion battery charger, 1.5 A max charge current, USB interface, 16-VQFN exposed-pad package, -40°C to 125°C junction","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":"USB","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24075","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.4V","Supplier Device Package":"16-VQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0300","priceTiers":[{"qty":1,"price":"$3.03000","currency":"USD"},{"qty":10,"price":"$2.72500","currency":"USD"},{"qty":25,"price":"$2.57040","currency":"USD"},{"qty":100,"price":"$2.19010","currency":"USD"},{"qty":250,"price":"$2.05640","currency":"USD"},{"qty":500,"price":"$1.79936","currency":"USD"},{"qty":1250,"price":"$1.49089","currency":"USD"},{"qty":2500,"price":"$1.45500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d4905d1bf65c1fac46a40664cbb63a39.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24075RGTT/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24075RGTT?","answer":"1.5 A max, set by an external resistor.
