The active-low, push-pull output drives the reset pin directly without an external pull-up resistor. ## Package and footprint — SOT-23-5 Housed in a SOT-23-5 package, the TPS3823-30DBVR uses the standard 5-pin supervisor footprint common across TI's TPS382x family. Surface-mount assembly is straightforward for reflow profiles typical of lead-free solders. The base product number is TPS3823, which covers multiple threshold options in the same SOT-23-5 footprint. The -30 suffix denotes the 2.63V threshold variant.","metaTitle":"TPS3823-30DBVR Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3823-30DBVR simple reset/power-on reset IC with 2.63V threshold, active-low push-pull output, 120ms timeout, -40°C to 85°C.","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":"120ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3823","Voltage - Threshold":"2.63V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3823-30DBVR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact reset threshold voltage of TPS3823-30DBVR?","answer":"The reset threshold voltage is 2.63V. This is the voltage at which the device asserts a reset on a monitored 3.3V rail."},{"question":"Can TPS3823-30DBVR be used to monitor a 3.3V rail?","answer":"Yes. The 2.63V threshold is approximately 80% of 3.3V, which is a typical undervoltage detection point for 3.3V logic supplies. The reset triggers when the rail falls below that level."},{"question":"Does TPS3823-30DBVR require an external pull-up resistor?","answer":"No. The output is push-pull, totem pole, so it drives the reset signal high or low without an external pull-up resistor.
