That threshold targets 5 V logic rails — the detector holds the reset output active until the supply recovers above the threshold plus hysteresis, then releases after a 180 ms minimum timeout. The open-drain output needs a pull-up resistor to the reset line's own rail; choose the pull-up value so the output sinks current within the device's rated capability at the reset voltage level. ## Industrial temperature range — where it fits The SOT-753 (SC-74A) package keeps the footprint small, but the thermal path is through the leads; in a still-air enclosure above 85°C, verify the junction temperature stays within the absolute maximum by checking the power dissipation from the pull-up current and any leakage. ## Active production — no LTB clock ticking No last-time-buy notice or successor has been issued for this order code.","metaTitle":"BD45472G-TR Voltage Detector, 4.7V Threshold, Active Low","metaDescription":"ROHM BD45472G-TR voltage detector with 4.7V threshold, active-low open-drain output, 180ms min reset timeout, -40°C to 105°C, SOT-753.","metaKeywords":null},"attributes":{"series":"BD45xxx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Voltage Detector","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"BD45xxx","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"180ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.7V","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"5-SSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.80000","currency":"USD"},{"qty":10,"price":"$0.70000","currency":"USD"},{"qty":25,"price":"$0.65720","currency":"USD"},{"qty":100,"price":"$0.53640","currency":"USD"},{"qty":250,"price":"$0.49820","currency":"USD"},{"qty":500,"price":"$0.42400","currency":"USD"},{"qty":1000,"price":"$0.33920","currency":"USD"},{"qty":3000,"price":"$0.32584","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7745a937f17681bdf03c6fde47aea6d7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BD45472G-TR and BD45472G?","answer":"The -TR suffix indicates Tape & Reel packaging for automated assembly; the base part number BD45472G is the same silicon in a different shipping medium.
