The open-drain output means a pull-up resistor to the monitored supply (or another rail up to the part's absolute maximum) is required to generate a logic-high when the supply is good. ## 20ms reset timeout — power-up sequencing The reset timeout is a minimum of 20ms, meaning after the supply rises above the 2.64V threshold, the part holds the reset output low for at least 20ms before releasing it. This delay allows the system power supply to stabilise and the oscillator to start before the processor or logic is released from reset — a standard requirement for reliable power-up sequencing. ## SOT-23-6 package and temperature grade Housed in a SOT-23-6 package (supplier device package SOT-23-6), this part is a surface-mount component suitable for compact PCB layouts with a 0.95mm pitch.","metaTitle":"TI TPS3813L30DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3813L30DBVRG4 simple reset/power-on reset IC with 2.64V threshold, active-low open-drain output, 20ms min reset timeout in SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Packaging":"Tape & Reel (TR)","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Reset Timeout":"20ms Minimum","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Base Product Number":"TPS3813","Voltage - Threshold":"2.64V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdcb50ac2bbb4403520bc84b0d95bb38.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3813L30DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3813L30DBVRG4 a direct replacement for TPS3813L30DBVR?","answer":"The base product number is TPS3813, and the suffix differences (DBVR vs DBVRG4) typically indicate packaging or environmental compliance variants (e.g., RoHS or lead-free plating). The electrical specifications — 2.64V threshold, active-low open-drain output, 20ms minimum reset timeout — are identical. Confirm the package marking and solder profile compatibility for your assembly process before substituting."},{"question":"Is TPS3813L30DBVRG4 suitable for 3.3V systems?","answer":"Yes. The 2.64V threshold is approximately 80% of a 3.3V rail, providing a typical undervoltage detection point that catches brownouts while ignoring normal supply ripple. The open-drain output interfaces directly with 3.3V logic when pulled up to the same rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3813L30DBVRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3813L30DBVRG4 when reusing this data.
