That threshold sits at the low end of the 1.8V tolerance band — it catches a brown-out before the downstream logic starts seeing undefined states, but won't trip on normal ripple. The output is push-pull, active-low, so it drives a reset input directly without needing an external pull-up resistor. ## Reset timeout — 10 ms minimum After VDD recovers above the threshold, the reset output stays low for a minimum of 10 ms before releasing. If your MCU needs a longer hold-off, you'll need a supervisor with an adjustable timeout or an external RC delay. Housed in a 5-pin SOT-23-5 (SC-74A) package, this is a surface-mount part with a 0.95 mm pitch — fits a standard two-layer board without fan-out issues. It does not extend to the 105°C or 125°C required for automotive under-hood or high-density power supplies. No NRND notice, no last-time-buy window, no announced end-of-life.","metaTitle":"TPS3836E18DBVR Simple Reset/Power-On Reset, 1.71V Threshold","metaDescription":"Texas Instruments TPS3836E18DBVR simple reset/power-on reset IC with 1.71V threshold, active-low push-pull output, 10ms min timeout.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"10ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3836","Voltage - Threshold":"1.71V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3836E18DBVR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3836E18DBVR work with a 1.8V supply?","answer":"Yes.
