It asserts a reset signal (active-low, open-drain output) when the monitored voltage drops below the 4.55V threshold and holds reset for a minimum of 120ms after the supply recovers. ## AEC-Q100 and the 125°C ceiling The SOT-23-5 package keeps the footprint small, but the real thermal limit is the junction temperature; at 125°C ambient the die is near its absolute maximum, so the board layout should keep the reset IC away from high-power components.","metaTitle":"TPS3828-50QDBVRQ1 Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3828-50QDBVRQ1 automotive AEC-Q100 simple reset IC, active-low open-drain output, 4.55V threshold, 120ms min reset timeout.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3828","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6cf730b73ae4455a53334f65b04f02cd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3828-50QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS3828-50QDBVRQ1?","answer":"No official replacement or successor is listed by Texas Instruments for the TPS3828-50QDBVRQ1. Any replacement would need to match the 4.55V threshold, active-low open-drain output, 120ms minimum reset timeout, SOT-23-5 footprint, and AEC-Q100 qualification. The TPS3828-50QDBVR (non-automotive grade) is a functional equivalent but lacks the AEC-Q100 rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3828-50QDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3828-50QDBVRQ1 when reusing this data.
