It asserts reset when the supply drops below 1.1V and holds it low for a minimum of 120 ms after the rail recovers, giving the downstream processor time to stabilize. ## 120 ms reset timeout and industrial temperature range The 120 ms minimum reset timeout is long enough to cover most power-supply ramp-up sequences for MCUs and SoCs, but short enough to avoid delaying system start-up. The 4-X2SON package is moisture-sensitive — store the reels dry per MSL guidelines.","metaTitle":"TPS3839G12DQNT – TI Simple Reset Supervisor, 1.1V Threshold","metaDescription":"Texas Instruments TPS3839G12DQNT: Simple Reset/Power-On Reset, 1.1V threshold, 120 ms timeout, active low push-pull output, -40°C to 85°C, 4-X2SON 1x1 mm.","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":"1.1V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"4-X2SON (1x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0200","priceTiers":[{"qty":1,"price":"$1.02000","currency":"USD"},{"qty":10,"price":"$0.91600","currency":"USD"},{"qty":25,"price":"$0.86960","currency":"USD"},{"qty":100,"price":"$0.71430","currency":"USD"},{"qty":250,"price":"$0.66776","currency":"USD"},{"qty":500,"price":"$0.59010","currency":"USD"},{"qty":1250,"price":"$0.46587","currency":"USD"},{"qty":2500,"price":"$0.43950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839G12DQNT/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3839G12DQNT?","answer":"The reset timeout is 120 ms minimum.
