Surface-mount only, supplied on Tape & Reel. ## Temperature grade and operating envelope The single-voltage monitor covers one rail; for multi-rail systems a separate supervisor per rail or a multi-channel part like the TPS386000 is the next step up. The base product number TPS3828 covers multiple threshold options (TPS3828-33, TPS3828-50); the DBVRG4 suffix denotes the SOT-23-5 package and tape-and-reel delivery.","metaTitle":"Texas Instruments TPS3828-50DBVRG4 Simple Reset/Power-On","metaDescription":"Texas Instruments TPS3828-50DBVRG4 simple reset/power-on reset IC, active-low open-drain output, 4.55V threshold, 120ms timeout, SOT-23-5.","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)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"SC-74A, SOT-753","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3828-50DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3828-50DBVRG4?","answer":"The reset timeout is a minimum of 120ms.
