The active-high, push-pull output drives the processor reset input directly without needing an external pull-up resistor. The part comes in a SOT-23-5 package, a five-pin surface-mount footprint. The supplier device package string SOT-23-5 is what the PCB footprint library uses. The base product number TPS3837 covers multiple threshold options; the suffix selects the 1.71V version, so ordering the correct variant is a matter of verifying the full order code against the BOM.","metaTitle":"TPS3837E18DBVT Simple Reset/Power-On Reset, 1.71V Threshold","metaDescription":"Texas Instruments TPS3837E18DBVT simple reset IC with 1.71V threshold, active-high push-pull output, 10ms 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":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High","Output":"Push-Pull, Totem Pole","Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3837","Voltage - Threshold":"1.71V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3837E18DBVT/alternatives.json"},"ai":{"faq":[{"question":"What is the exact reset threshold voltage of TPS3837E18DBVT?","answer":"The reset threshold voltage is 1.71V. This is the trip point for a nominal 1.8V supply rail — the reset asserts when the monitored voltage falls below 1.71V and de-asserts after a 10ms timeout once the supply recovers above it."},{"question":"Does TPS3837E18DBVT have an active high or active low reset?","answer":"The reset output is active high. The output goes high when the monitored voltage drops below the threshold and stays high through the timeout period after recovery. This is the correct polarity for processors that require a high-true reset input."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3837E18DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3837E18DBVT when reusing this data.
