The output is open-drain, active low, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. ## 100 ms timeout and industrial temperature range After the supply rises above the threshold, the reset output stays low for a minimum of 100 ms before releasing.","metaTitle":"TPS3128E15DBVR Simple Reset/Power-On Reset IC","metaDescription":"TI TPS3128E15DBVR simple reset IC with 1.43V threshold, active-low open-drain output, 100ms timeout, -40°C to 85°C.","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":"100ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3128","Voltage - Threshold":"1.43V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2225","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33ce582e7a8405bef9aabe534ac434b3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3128E15DBVR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS3128E15DBVR be used with a 1.8V powered microcontroller?","answer":"Yes. The 1.43V threshold is well below a nominal 1.8V rail, providing roughly 370 mV of margin for brownout detection.
