The output is push-pull, totem-pole, active low — no external pull-up resistor needed. It drives the reset input of an MCU, FPGA, or DSP directly. The SC-70-5 package (also known as SOT-353) is a 5-pin surface-mount package that fits tight board layouts. The SC-70-5 footprint is shared with many other TI reset supervisors — if you have a board already laid out for a TPS380x or TPS382x in the same package, this part drops in without a layout change. The 5-pin SOT-353 land pattern is standard; no exotic pad geometry.","metaTitle":"TPS3801I50DCKR Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3801I50DCKR simple reset/power-on reset IC with 4.55V threshold, active-low push-pull output, 120ms min reset 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":"120ms Minimum","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3801","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/353ab7aa064810346ed7462973d871e3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3801I50DCKR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3801I50DCKR?","answer":"The reset timeout is a minimum of 120 ms. That is the guaranteed time the reset output stays low after the supply crosses the 4.55 V threshold — enough for most MCUs and FPGAs to complete their internal power-up sequence."},{"question":"Is the reset output of TPS3801I50DCKR active high or active low?","answer":"Active low. The reset output goes low when the monitored voltage falls below the 4.55 V threshold and stays low for the 120 ms timeout after the supply recovers. It is a push-pull output, so it drives the reset pin directly without an external pull-up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3801I50DCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3801I50DCKR when reusing this data.
