The 120ms minimum reset timeout ensures the downstream processor sees a full reset pulse before startup, covering the typical 100ms requirement with margin. This is a Simple Reset/Power-On Reset type — no adjustable delay or manual reset input. ## Industrial temp grade and 1mm² package Compared to the TLV803EA29VDBZR (open-drain output, 130ms timeout, -40°C to 125°C), the TPS3831L30DQNR's push-pull output saves the pull-up resistor, but the TLV803 offers a wider temperature range and a lower 2.93V threshold option. The TPS3831L30DQNR's 2.63V threshold is the right fit for a 2.7V or 2.8V rail — confirm your supply tolerance against the 2.63V min before committing. ## Active production, tape-and-reel packaging","metaTitle":"TPS3831L30DQNR TI Simple Reset Supervisor, 2.63V, Active Low","metaDescription":"Texas Instruments TPS3831L30DQNR: Simple Reset/Power-On Reset, 2.63V threshold, 120ms min timeout, push-pull output, -40°C to 85°C, 4-X2SON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"4-XDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3831","Voltage - Threshold":"2.63V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"4-X2SON (1x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3400","priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.19800","currency":"USD"},{"qty":25,"price":"$1.13680","currency":"USD"},{"qty":100,"price":"$0.93380","currency":"USD"},{"qty":250,"price":"$0.87284","currency":"USD"},{"qty":500,"price":"$0.77136","currency":"USD"},{"qty":1000,"price":"$0.60897","currency":"USD"},{"qty":3000,"price":"$0.43050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/171738cafab7c3368a7e7902c6be9c34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3831L30DQNR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout and threshold voltage of TPS3831L30DQNR?","answer":"The reset timeout is 120ms minimum. The voltage threshold is 2.63V, which monitors a single rail — typically a 2.7V or 2.8V supply. The output is active-low push-pull, so no external pull-up resistor is needed."},{"question":"Is TPS3831L30DQNR equivalent to TPS3831L30DBVR?","answer":"Both parts share the same base number (TPS3831) and electrical ratings — 2.63V threshold, 120ms timeout, push-pull output. The difference is the package: the DQNR suffix is 4-X2SON (1x1), while the DBVR suffix is SOT-23-5.
