This threshold is tailored for 1.8V supply monitoring — the reset asserts when the rail drops below 1.67V, holding the system in reset for a minimum of 120ms after the supply recovers. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, simplifying the BOM on a processor or FPGA reset input. ## Industrial temperature and package footprint","metaTitle":"TPS3839G18DQNT – Texas Instruments Simple Reset/Power-On","metaDescription":"TPS3839G18DQNT from TI: Active-low push-pull reset IC, 1.67V threshold, 120ms min timeout, -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":"TPS3839","Voltage - Threshold":"1.67V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"4-X2SON (1x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0100","priceTiers":[{"qty":1,"price":"$1.01000","currency":"USD"},{"qty":10,"price":"$0.90300","currency":"USD"},{"qty":25,"price":"$0.85680","currency":"USD"},{"qty":100,"price":"$0.70380","currency":"USD"},{"qty":250,"price":"$0.65788","currency":"USD"},{"qty":500,"price":"$0.58138","currency":"USD"},{"qty":1250,"price":"$0.45898","currency":"USD"},{"qty":2500,"price":"$0.43300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839G18DQNT/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3839G18DQNT?","answer":"The reset timeout is 120ms minimum. After the supply rises above the threshold, the output remains low for at least 120ms to allow the system oscillator and power rails to stabilise before the processor starts executing code."},{"question":"What package is TPS3839G18DQNT available in?","answer":"The TPS3839G18DQNT is supplied in a 4-X2SON package measuring 1x1 mm with an exposed pad. The supplier device package is 4-X2SON (1x1)."},{"question":"Can TPS3839G18DQNT be used for 1.8V systems?","answer":"Yes, the 1.67V threshold is designed for monitoring a 1.8V nominal supply. The reset asserts when the rail drops to 1.67V, providing a typical undervoltage window of about 130 mV below the nominal 1.8V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3839G18DQNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3839G18DQNT when reusing this data.
