This threshold is set for 3.3V nominal systems — it trips before the logic supply falls out of spec, holding the processor in reset until the rail recovers and the 150ms minimum timeout expires. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, saving one component per BOM. This supervisor is suited for factory automation, outdoor telecom cabinets, motor drives, and other equipment that sees seasonal temperature swings but not extended under-hood or downhole extremes. The SOT-23-3 package keeps the footprint small — three pins, one for VCC, one for GND, one for the /RST output. The ROHS3 compliance is confirmed — no lead, no restricted substances in the SOT-23-3 package. For the sourcing desk: this is a standard-channel BOM line, quoted to order against RFQ quantities. ## 150ms timeout — why it matters for power sequencing The 150ms minimum reset timeout is the window the supervisor holds the reset line low after VCC rises above the 2.925V threshold. If the downstream MCU or SoC requires a longer reset pulse, this part may not be the right fit — check the processor's minimum reset hold time against this 150ms floor.","metaTitle":"Microchip MCP100T-300I/TT Simple Reset/Power-On Reset","metaDescription":"Microchip MCP100T-300I/TT simple reset/power-on reset IC, 2.925V threshold, active-low push-pull output, 150ms min timeout, SOT-23-3, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"150ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.925V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.49","priceTiers":[{"qty":1,"price":"$0.49000","currency":"USD"},{"qty":25,"price":"$0.42400","currency":"USD"},{"qty":100,"price":"$0.37100","currency":"USD"},{"qty":3000,"price":"$0.37100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c4c92cbca6d786502b586281a096db67.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MCP100T-300I%2FTT/alternatives.json"},"ai":{"faq":[{"question":"Is MCP100T-300I/TT RoHS compliant?","answer":"Yes, it is ROHS3 compliant — no lead or restricted substances in the SOT-23-3 package."},{"question":"Can MCP100T-300I/TT be used with 3.3V systems?","answer":"Yes. The 2.925V threshold is set to monitor a 3.3V rail — it asserts reset when the supply drops below 2.925V, which is above the minimum operating voltage of most 3.3V logic. This is a standard 3.3V supervisor, not a 5V or 1.8V part."},{"question":"How does MCP100T-300I/TT compare to MCP100-300I/TT?","answer":"The order codes are nearly identical — the 'T' in MCP100T-300I/TT indicates Tape & Reel packaging, while MCP100-300I/TT is also Tape & Reel. The electrical specifications (2.925V threshold, 150ms timeout, push-pull output, SOT-23-3 package, -40°C to 85°C range) are the same. The difference is in the ordering code suffix convention; functionally they are interchangeable for the same BOM position."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MCP100T-300I-TT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MCP100T-300I-TT when reusing this data.
