The 120ms minimum reset timeout gives the downstream processor or FPGA time to stabilize after power-up or a brown-out event. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, saving a component on the BOM. The active-low reset is the standard polarity for most MCU and DSP reset inputs. Texas Instruments lists this as a current production part, so BOM planners can source it without near-term obsolescence risk. ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free soldering processes.","metaTitle":"TPS3831G18DQNR Texas Instruments Simple Reset/Power-On","metaDescription":"TPS3831G18DQNR Texas Instruments simple reset/power-on reset IC, 1.67V threshold, 120ms min timeout, active low push-pull output, -40°C to 85°C, 4-X2SON","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":"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":"$1.3400","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":"$0.57450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/171738cafab7c3368a7e7902c6be9c34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3831G18DQNR/alternatives.json"},"ai":{"faq":[{"question":"Can the TPS3831G18DQNR replace a TPS3831G18DGN?","answer":"The TPS3831G18DQNR and TPS3831G18DGN share the same base product number TPS3831 and the same electrical specs (1.67V threshold, 120ms timeout, push-pull output). The difference is the package: the DQNR is in a 4-X2SON (1x1 mm), while the DGN is in a different package (SOT-23).

The 1.67V threshold is designed to monitor a nominal 1.8V rail, providing approximately 130mV of margin before the reset is triggered.
