The output is push-pull, active-low, so it can drive the reset input of an MCU or FPGA without an external pull-up resistor. ## Threshold, timeout, and temperature boundaries The 3.08V threshold is set for a nominal 3.3V rail — it trips before the supply falls below the minimum operating voltage of typical 3.3V logic. ## Package and PCB layout consideration The device comes in a 4-X2SON package measuring 1x1 mm. The 4-pin footprint is straightforward to hand-solder with a fine-tip iron, but the pad pitch is tight; a stencil is recommended for reflow assembly. The part is ROHS3 compliant.","metaTitle":"TPS3839G33DQNR – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3839G33DQNR Simple Reset/Power-On Reset IC with 3.08V threshold, active-low push-pull output, 120ms timeout, -40°C to 85°C range, 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":"TPS3839","Voltage - Threshold":"3.08V","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":1000,"price":"$0.46587","currency":"USD"},{"qty":3000,"price":"$0.43950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839G33DQNR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional equivalent to the TPS3839G33DQNR?","answer":"The TLV803EA29VDBZR is a functional peer: it is also a simple reset/power-on reset IC with active-low output, but uses an open-drain output (requires a pull-up resistor) and has a 2.93V threshold with a 130 ms minimum timeout.
