That threshold is chosen for a 3.3V nominal rail — it trips before the supply falls far enough to corrupt SRAM or cause flash read errors, but stays above the brownout zone of most Cortex-M and 8051 MCUs.","metaTitle":"TPS3823-30DBVT – Texas Instruments Simple Reset/Power-On","metaDescription":"Texas Instruments TPS3823-30DBVT: Simple Reset/Power-On Reset, Active Low, Push-Pull output, 2.63V threshold, 120ms min timeout, -40°C to 85°C, SOT-23-5.","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":"120ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3823","Voltage - Threshold":"2.63V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8900","priceTiers":[{"qty":1,"price":"$1.89000","currency":"USD"},{"qty":10,"price":"$1.70200","currency":"USD"},{"qty":25,"price":"$1.60600","currency":"USD"},{"qty":100,"price":"$1.36820","currency":"USD"},{"qty":250,"price":"$1.28472","currency":"USD"},{"qty":500,"price":"$1.12412","currency":"USD"},{"qty":1250,"price":"$0.93142","currency":"USD"},{"qty":2500,"price":"$0.90900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3823-30DBVT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for TPS3823-30DBVT?","answer":"The TLV803EA29VDBZR is a close functional alternative — also a Simple Reset/Power-On Reset with Active Low output, but its output is Open Drain (needs a pull-up resistor) and its reset timeout is 130ms minimum versus 120ms. The threshold voltage differs: 2.63V for the TPS3823-30DBVT versus 2.93V for the TLV803EA29VDBZR. Verify the threshold matches your supply rail before substituting."},{"question":"Is TPS3823-30DBVT compatible with 3.3V systems?","answer":"Yes — the 2.63V threshold is designed for a 3.3V nominal rail. The reset asserts when the supply falls below 2.63V, which is above the minimum operating voltage of most 3.3V MCUs and FPGAs. For a 3.0V rail, the threshold is too close to the operating floor — use a supervisor with a lower threshold instead."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3823-30DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3823-30DBVT when reusing this data.
