When the supply drops below this level, the active-low reset output asserts and holds the system in reset for at least 15ms after the rail recovers. The push-pull output drives directly to the downstream MCU or FPGA reset input without an external pull-up resistor.","metaTitle":"TPS3820-50DBVRQ1G4 Simple Reset/Power-On Reset, AEC-Q100","metaDescription":"Texas Instruments TPS3820-50DBVRQ1G4 simple reset IC, active-low push-pull output, 4.55V threshold, 15ms min timeout, -40°C to 125°C, AEC-Q100 qualified.","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":"Push-Pull, Totem Pole","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"15ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3820","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":"$2.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55b80fccb6c7a1290829640dc73eb79a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3820-50DBVRQ1G4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3820-50DBVRQ1G4 automotive qualified?","answer":"Yes. The TPS3820-50DBVRQ1G4 is part of the Automotive, AEC-Q100 series. An OEM auditor will expect AEC-Q100 grade documentation — the part number suffix Q1 confirms the automotive qualification tier."},{"question":"What is the difference between TPS3820-50 and TPS3823?","answer":"The TPS3820-50 has a fixed 4.55V threshold for monitoring a 5V rail, while the TPS3823 typically has a different threshold voltage (e.g., 3.08V for a 3.3V rail). Both share the same SOT-23-5 package and active-low push-pull output, so they are pin-compatible across the family. The correct choice depends entirely on the supply voltage being supervised."},{"question":"What is the reset timeout of TPS3820-50?","answer":"The reset timeout is a minimum of 15ms. This is the guaranteed minimum delay from when the supply rises above the threshold to when the reset output de-asserts. The actual timeout is longer and is specified in the datasheet; the 15ms floor ensures the system power supply has stabilised before the processor starts executing code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3820-50DBVRQ1G4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3820-50DBVRQ1G4 when reusing this data.
