Its 4.5V threshold is set for monitoring a nominal 5V supply rail, asserting a reset when the rail drops below that level. ## Active-low push-pull — no external pull-up The reset output is active-low push-pull (totem pole), meaning it drives both high and low without requiring an external pull-up resistor. This simplifies the BOM and saves a resistor slot on dense automotive PCBs. ## Temperature grade and deployment The AEC-Q100 qualification adds the stress-tested reliability required for production automotive modules. ## Package and footprint Supplied in a 5-pin SC-74A (SOT-753) surface-mount package, also designated as 5-SSOP. The small footprint fits space-constrained ECU layouts. Available in Tape & Reel for automated assembly.","metaTitle":"ROHM BD49E45G-MTR Voltage Detector, 4.5V Threshold, AEC-Q100","metaDescription":"ROHM BD49E45G-MTR voltage detector with 4.5V threshold, push-pull active-low reset, -40°C to 105°C, AEC-Q100.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, BD49Exxx-M","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Voltage Detector","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"Automotive, AEC-Q100, BD49Exxx-M","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.5V","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 BD49E45G-MTR suitable for automotive applications?","answer":"Yes."},{"question":"Does BD49E45G-MTR have a push-pull or open-drain output?","answer":"Push-pull (totem pole) output — it drives both high and low without an external pull-up resistor."},{"question":"What is the equivalent part for BD49E45G-MTR?","answer":"The closest functional peer is BD4929G-TR from the same BD49xxx family, but its threshold voltage differs — BD4929G-TR monitors a different rail.
