The active-low, open-drain output lets you pull the reset signal to any voltage up to the absolute maximum of the output transistor, which is useful when the supervisor runs on a different rail than the monitored supply. The open-drain topology also allows wired-OR connections with other reset sources — common in multi-rail systems where any fault must trigger a global reset. ## AEC-Q100 Grade — Audit-Ready Qualification This part carries AEC-Q100 qualification as part of the BD52Exxx-M series, which means it has passed the stress tests (temperature cycling, ESD, latch-up, etc.) required for automotive PPAP submissions. Active lifecycle status means ROHM continues to manufacture it; no last-time-buy or successor has been announced. ## Package and Footprint — SC-74A / SOT-753 The SC-74A (SOT-753) package is a 5-pin surface-mount footprint, also designated as 5-SSOP by ROHM. It fits standard reflow profiles; no exposed pad, so thermal dissipation relies on the copper trace area connected to the GND pin. The small footprint suits space-constrained ECU or sensor module designs.","metaTitle":"BD52E32G-MTR Voltage Detector, AEC-Q100, 3.2V Threshold","metaDescription":"ROHM BD52E32G-MTR is an AEC-Q100 qualified voltage detector with 3.2V threshold, active-low open-drain output in SC-74A package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, BD52Exxx-M","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, BD52Exxx-M","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.2V","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"5-SSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.67200","currency":"USD"},{"qty":25,"price":"$0.63080","currency":"USD"},{"qty":100,"price":"$0.51490","currency":"USD"},{"qty":250,"price":"$0.47828","currency":"USD"},{"qty":500,"price":"$0.40704","currency":"USD"},{"qty":1000,"price":"$0.32563","currency":"USD"},{"qty":3000,"price":"$0.29510","currency":"USD"},{"qty":6000,"price":"$0.28800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c71c101c3abc69c2a7b379ec87170cb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type and reset polarity of BD52E32G-MTR?","answer":"The output is open-drain (or open-collector) and the reset is active-low.
