It holds the reset output low for a minimum of 240ms after the supply returns above the threshold, giving the system time to stabilize before the processor starts. The SC-70-5 package (also known as SOT-353) is a compact 5-lead surface-mount package that fits well in portable or densely populated designs.","metaTitle":"TPS3802K33DCKR Texas Instruments Simple Reset/Power-On","metaDescription":"TPS3802K33DCKR from TI: Simple Reset/Power-On Reset, Active Low, Push-Pull output, 2.93V threshold, 240ms min timeout, SC-70-5, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"240ms Minimum","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3802","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6000","priceTiers":[{"qty":1,"price":"$1.60000","currency":"USD"},{"qty":10,"price":"$1.43500","currency":"USD"},{"qty":25,"price":"$1.35360","currency":"USD"},{"qty":100,"price":"$1.15330","currency":"USD"},{"qty":250,"price":"$1.08288","currency":"USD"},{"qty":500,"price":"$0.94754","currency":"USD"},{"qty":1000,"price":"$0.78510","currency":"USD"},{"qty":3000,"price":"$0.76620","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/353ab7aa064810346ed7462973d871e3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3802K33DCKR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3802K33DCKR suitable for monitoring a 3.3V supply?","answer":"Yes. The 2.93V threshold is set to assert reset when a 3.3V rail drops below approximately 88% of its nominal value. This is a common threshold for 3.3V logic systems, ensuring the processor resets before the supply falls below the minimum operating voltage of typical 3.3V devices."},{"question":"Does TPS3802K33DCKR have a push-pull or open-drain output?","answer":"It has a push-pull (totem pole) output. This means the reset output is actively driven both high and low, so no external pull-up resistor is needed. The output is active low, meaning it goes low during reset."},{"question":"What is the closest functional alternative to TPS3802K33DCKR?","answer":"The TLV803EA29VDBZR and TLV803ED29DBZR are similar voltage supervisors with a 2.93V threshold, but they use an open-drain output and have different reset timeout periods (130ms and 33ms respectively). The TPS3802K33DCKR's push-pull output is a key difference — if your design requires an open-drain output for wired-OR reset sharing, the TLV803 variants are alternatives."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3802K33DCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3802K33DCKR when reusing this data.
