It is a Simple Reset/Power-On Reset type, meaning it holds the reset output active for a typical 30 µs after the supply recovers, giving the system time to stabilize. The reset is active low, and the output is open drain or open collector — so on a field swap or a fresh board, remember that pin needs a pull-up resistor to whatever logic rail the downstream reset input expects. No pull-up, no reset signal. That is the one thing that trips people up when they drop this into a design without checking the output stage. ## 4.6V threshold — what it means for your rail The 4.6V threshold is set for monitoring a nominal 5V supply. When the 5V rail droops to 4.6V or below, the reset fires. That gives about 8% margin below 5V, which is typical for catching brownouts or slow-start ramps without nuisance resets on normal ripple. If your system runs on 3.3V or 2.5V, this is not the part — the threshold is fixed, not adjustable. For a 5V industrial controller, motor drive, or PLC module, it is a clean fit. ## Industrial temperature range — field-ready Rated for -40°C to 85°C ambient, so it handles outdoor telecom cabinets, factory floor gear, and unheated enclosures without drama. No special derating needed across that range for the reset timing or threshold accuracy — the datasheet typicals hold. ## Package and footprint — SOT-23-4 Housed in a SOT-23-4 (TO-253-4 / TO-253AA) package, surface mount. Four pins, small footprint — easy to hand-solder if you are doing a field repair or a prototype rework. The marking is usually minimal, so check the orientation against the datasheet drawing before you place it. No exposed pad, no thermal vias needed; it dissipates milliwatts. ## Lifecycle and compliance — active, but watch the RoHS flag Listed as Active in production — no end-of-life notice, no last-time-buy pressure. You can design it in today without worrying about a sudden EOL. One catch: it is marked RoHS non-compliant. If your BOM requires RoHS 5/6 or 6/6 exemption tracking, this part may not pass audit. Check your exemption policy before committing. For legacy or military/industrial builds that allow lead-bearing solder, it is fine.","metaTitle":"MAX6808US26-T Simple Reset/Power-On Reset, 4.6V Threshold","metaDescription":"MAX6808US26-T from Maxim Integrated is a Simple Reset/Power-On Reset IC with 4.6V threshold, active-low open-drain output, 30µs timeout, SOT-23-4.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"30µs Typical","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.6V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.32","stockQuantity":0,"priceTiers":[{"qty":228,"price":"$1.32000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/27f76edb71568d644060ef5fadee5881.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6808US26-T RoHS compliant?","answer":"No, it is listed as RoHS non-compliant.
