The active-low, open-drain output asserts when the monitored voltage drops below that threshold, and releases when it rises above the reset voltage (typically 4.2V plus hysteresis). The open-drain topology means the output requires an external pull-up resistor to the logic supply — the designer chooses the pull-up voltage independent of the monitored rail. ## Temperature grade and package — fits under-hood and cabin ECU profiles The SC-74A (SOT-753) package, also designated as 5-SSOP, is a 5-pin surface-mount footprint common across ROHM's voltage detector family. The small body saves board area but the 0.95 mm pitch is still hand-solderable for prototype rework.","metaTitle":"ROHM BD48E42G-MTR Voltage Detector, AEC-Q100, 4.2V Threshold","metaDescription":"ROHM BD48E42G-MTR AEC-Q100 voltage detector, 4.2V threshold, active-low open-drain output, -40°C to 105°C, SC-74A package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, BD48Exx","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":"Automotive, AEC-Q100, BD48Exx","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.2V","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"5-SSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.73","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.73000","currency":"USD"},{"qty":10,"price":"$0.64400","currency":"USD"},{"qty":25,"price":"$0.60480","currency":"USD"},{"qty":100,"price":"$0.49350","currency":"USD"},{"qty":250,"price":"$0.45836","currency":"USD"},{"qty":500,"price":"$0.39008","currency":"USD"},{"qty":1000,"price":"$0.31206","currency":"USD"},{"qty":3000,"price":"$0.28281","currency":"USD"},{"qty":6000,"price":"$0.27600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ac731e29f72730f99e122542c6ac41a6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BD48E42G-MTR AEC-Q100 qualified?","answer":"Yes, the BD48E42G-MTR is part of the Automotive, AEC-Q100 series BD48Exx, confirming qualification for automotive-grade applications."},{"question":"What is the closest functional equivalent to BD48E42G-MTR?","answer":"The BD45422G-TR is a functional peer from ROHM's BD45xxx series — same active-low, open-drain output, same -40°C to 105°C range, and same SC-74A package.
