Housed in a 4-lead SC-70-4 (SC-82A) package, it occupies minimal board area and suits compact designs where a single supervisor must watch both a 5 V rail and a secondary supply. ## 140 ms minimum reset timeout — why it matters The reset output stays asserted for at least 140 ms after all monitored voltages rise above their thresholds — this guarantees the downstream system (MCU, FPGA) has time to stabilise its power and oscillator before the reset lifts, preventing a brown-out restart.","metaTitle":"MAX6388XS46D3+ Power Supply Monitor, 4.63V Threshold","metaDescription":"MAX6388XS46D3+ Power Supply Monitor from Analog Devices, active-high reset, 140ms timeout, monitors two voltages, SC-70-4 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Power Supply Monitor","Reset":"Active High","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-82A, SOT-343","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.63V, Adj","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SC-70-4","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2a43ef6f52c719a0bf0ab10173c69901.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the 4.63 V threshold mean for a 5 V rail?","answer":"The 4.63 V fixed threshold on channel 1 monitors a nominal 5 V supply — the reset asserts when the rail dips below 4.63 V, providing a typical undervoltage trip point about 7% below the nominal voltage, which catches brown-outs before the downstream logic sees a glitch."},{"question":"Can the MAX6388XS46D3+ be reworked by hand?","answer":"Yes — the SC-70-4 package is small but reworkable with a hot-air station at 300°C for 30 seconds. The exposed pad is absent (standard SC-70), so no thermal pad alignment is needed.
