No external pull-up resistor is needed, which saves a component on the BOM. ## Package and temperature grade The small body suits space-constrained designs like portable instrumentation or sensor modules where a supervisor is needed without dedicating board area. Rated for operation from -40°C to 105°C ambient, it covers industrial temperature ranges — motor drives, power supplies, and outdoor telecom equipment that see thermal cycling stay within the guaranteed operating envelope.","metaTitle":"STM1815SWX7F Simple Reset/Power-On Reset, 2.88V Threshold","metaDescription":"STMicroelectronics STM1815SWX7F Simple Reset/Power-On Reset IC, 2.88V threshold, active-low push-pull output, 100ms timeout, SOT-23-3, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"100ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.88V","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.19700","currency":"USD"},{"qty":25,"price":"$1.13640","currency":"USD"},{"qty":100,"price":"$0.93350","currency":"USD"},{"qty":250,"price":"$0.87264","currency":"USD"},{"qty":500,"price":"$0.77116","currency":"USD"},{"qty":1000,"price":"$0.67008","currency":"USD"},{"qty":3000,"price":"$0.67007","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/da2bfc282b9685e2e635162875122e27.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM1815SWX7F/alternatives.json"},"ai":{"faq":[{"question":"What is the reset polarity of the STM1815SWX7F?","answer":"The reset is active low — the output pin goes low when the monitored voltage falls below the 2.88 V threshold, and stays low for the 100 ms minimum timeout after the supply recovers."},{"question":"How does the STM1815SWX7F compare to the STM1817RWX7F?","answer":"Both share the same SOT-23-3 package, 100 ms timeout, and -40°C to 105°C range.
