The open-drain output pulls low when VDD drops below the 1.71 V threshold; it requires an external pull-up resistor to the supervisor's supply or the monitored rail. The single-voltage monitor suits a dedicated core-supply watchdog in an ECU or sensor module. ## SOT-23-5 footprint Housed in a SOT-23-5 package (SC-74A, SOT-753), surface-mount only. The five-pin layout is standard for single-voltage supervisors in this family — the pinout matches other TPS3838 variants, so a board laid out for this part can accept a different threshold version with the same base number if the voltage changes in a future design revision.","metaTitle":"TPS3838E18QDBVRQ1 Simple Reset/POR, AEC-Q100","metaDescription":"Texas Instruments TPS3838E18QDBVRQ1 automotive simple reset/power-on reset IC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"1.71V","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68bd76a1a78d983ca3b9ca674d45cee5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838E18QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3838E18QDBVRQ1 have automotive qualification?","answer":"Yes, the TPS3838E18QDBVRQ1 is part of the Automotive, AEC-Q100 series, meaning it was qualified for automotive-grade reliability and temperature range."},{"question":"What is the replacement for TPS3838E18QDBVRQ1?","answer":"No official replacement or successor order code is listed on the lifecycle record for the TPS3838E18QDBVRQ1.
