It handles supply voltages from 3V to 20V and delivers up to 5A continuous output, making it a fit for 3.3V, 5V, 12V, and 19V rails in telecom, datacom, industrial, and general-purpose systems where you need controlled power-up and fault isolation. The operating temperature range of -40°C to 125°C covers industrial cabinets and under-hood automotive environments, not just climate-controlled racks. ## Protection features you can set This controller gives you programmable fault handling: auto retry, circuit breaker, current limit, fault timeout, and latched fault. That means you can decide whether the part resets itself after an overcurrent event or stays off until you cycle power — useful for different maintenance philosophies. The UVLO (undervoltage lockout) and thermal limit are fixed on-chip, so the part won't try to turn on below the supply threshold or cook itself. ## Active production — no LTB clock ticking The TPS2420RSAT is listed as Active with ROHS3 compliance. No last-time-buy notice, no end-of-life announcement. For a BOM line that needs to stay qualified for the next several years, this part is a safe bet — you aren't hunting for a replacement mid-production.","metaTitle":"TPS2420RSAT Hot Swap Controller, 5A, 3V-20V, 16-QFN","metaDescription":"TI TPS2420RSAT hot swap controller with integrated switch, 5A output, 3V-20V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Thermal Limit, UVLO","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"16-VQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 20V","Internal Switch(s)":"Yes","Number of Channels":"1","Operating Temperature":"-40°C ~ 125°C","Programmable Features":"Auto Retry, Circuit Breaker, Current Limit, Fault Timeout, Latched Fault","Current - Output (Max)":"5A","Supplier Device Package":"16-QFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.71000","currency":"USD"},{"qty":10,"price":"$3.33000","currency":"USD"},{"qty":25,"price":"$3.14800","currency":"USD"},{"qty":100,"price":"$2.72840","currency":"USD"},{"qty":250,"price":"$2.58852","currency":"USD"},{"qty":500,"price":"$2.32268","currency":"USD"},{"qty":1250,"price":"$1.98000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9365344a06d9a2c86873049acd4a395e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can TPS2420RSAT be used as a replacement for TPS2420?","answer":"The TPS2420 base part and the TPS2420RSAT share the same core hot-swap controller function. The 'RSAT' suffix indicates the reel packaging (Tape & Reel) and the 16-QFN package variant. For a direct drop-in, verify the package footprint and pinout match your board — the base TPS2420 may come in a different package or lead finish."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2420RSAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2420RSAT when reusing this data.
