The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different voltage domain. ## 120 ms reset timeout — why it matters for processor boot If the timeout were shorter, a fast-rising supply could release reset before the clock is valid, leading to erratic boot behaviour. This part is a drop-in fit for any 3.3V MCU or FPGA that expects an active-low reset with a 100–200 ms delay. ## Industrial temperature range and SOT-23-5 package The base product number TPS3828 covers multiple voltage threshold options (2.63V, 2.93V, 3.08V, 4.38V) in the same pinout, so a BOM change to a different threshold does not require a layout revision.","metaTitle":"TPS3828-33DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3828-33DBVRG4 simple reset/power-on reset IC with 2.93V threshold, active-low open-drain output, 120ms min reset timeout, -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","lifecycle_stage":"eol_hot","Base Product Number":"TPS3828","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3828-33DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3828-33DBVRG4?","answer":"The reset timeout is 120 ms minimum.
