The 10ms minimum reset timeout holds the reset line low long enough for the downstream processor or FPGA to complete its internal initialization sequence before the reset is released. This is a standard TI supervisor part number in the TPS3838 family, available through independent distribution channels. The SOT-23-5 package (SC-74A, SOT-753 footprint) is a common small-outline transistor package with five leads, surface-mount only. The 0.95 mm pin pitch and 2.9 mm body length fit well on compact boards where a supervisor is placed near the monitored rail's decoupling capacitors.","metaTitle":"TPS3838E18DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3838E18DBVTG4 simple reset IC, active-low open-drain output, 1.71V threshold, 10ms min timeout, -40°C to 85°C, SOT-23-5.","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":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838E18DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"Can TPS3838E18DBVTG4 replace TPS3838E18DBVT?","answer":"The TPS3838E18DBVTG4 and TPS3838E18DBVT share the same base product number TPS3838 and the same 1.71V threshold. The suffix difference typically indicates packaging or tape-and-reel variation. They are functionally identical and pin-compatible, but verify the specific package code (SOT-23-5) matches your board footprint before substituting."},{"question":"What is the reset timeout for TPS3838E18DBVTG4?","answer":"The reset timeout is 10ms minimum. This is the guaranteed minimum pulse width the reset output stays low after the monitored voltage rises above the threshold. The actual timeout may be longer; the datasheet should be consulted for the typical and maximum values."},{"question":"Is TPS3838E18DBVTG4 active low or active high?","answer":"The reset output is active low. The output goes low when the monitored voltage falls below the 1.71V threshold and remains low for the 10ms minimum timeout after the voltage recovers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3838E18DBVTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3838E18DBVTG4 when reusing this data.
