The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button, pulling to whatever logic voltage the pull-up resistor connects to. ## Industrial temperature and SOT-23-5 footprint ## Open-drain output — pull-up resistor required Because the output is open drain, the reset signal floats unless a pull-up resistor connects it to the logic supply rail. The 120ms timeout is a minimum; the actual timeout can be longer depending on the internal oscillator tolerance and temperature, so budget margin in any timing-critical power-up sequence.","metaTitle":"TI TPS3828-50DBVT Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3828-50DBVT Simple Reset/Power-On Reset IC, active-low open-drain output, 4.55V threshold, 120ms timeout, SOT-23-5, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","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":"TPS3828","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3828-50DBVT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS3828-50DBVT and TPS3828-33DBVT?","answer":"The TPS3828-50DBVT has a 4.55V threshold for monitoring a 5V supply rail, while the TPS3828-33DBVT has a lower threshold (typically 2.93V) for a 3.3V rail. Both share the same SOT-23-5 package, active-low open-drain output, and 120ms minimum reset timeout — the only difference is the voltage threshold and the intended supply voltage."},{"question":"Can TPS3828-50DBVT be used with a 5V supply?","answer":"Yes, the 4.55V threshold is specifically set for a nominal 5V supply rail. The supervisor asserts reset when the rail drops below 4.55V, which is the standard undervoltage threshold for a 5V system (typically 10% below nominal)."},{"question":"What is the reset timeout of TPS3828-50DBVT?","answer":"The reset timeout is a minimum of 120ms. After the monitored voltage rises above the 4.55V threshold, the output remains low for at least 120ms before releasing the reset signal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3828-50DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3828-50DBVT when reusing this data.
