It monitors a single voltage rail and asserts a reset signal when the supply drops below the 3.08 V threshold, holding reset for a minimum of 140 ms after the rail recovers. The push-pull, active-low output drives directly into the reset input of an MCU, DSP, or FPGA without an external pull-up resistor. Rated from -40°C to 125°C, it suits industrial controllers, automotive ECUs, and base-station power sequencers that need a reliable brownout monitor in a compact SOT-23-5 footprint. ## RoHS non-compliant — check your BOM requirements The MAX823TEUK is marked RoHS non-compliant. That means it contains lead (Pb) in the solder finish or internal construction, which exempts it from ROHS restrictions only if your product falls under a specific exemption (e.g., medical, aerospace, or high-reliability industrial). For EU or China RoHS markets, you will need a compliant alternate — the MAX823TEUK+T is the lead-free version, though the evidence does not confirm exact pin compatibility. Verify the alternate before swapping. ## Active production — no LTB risk That makes it safe to specify into new designs and stable for ongoing production builds. The part is available through independent distribution channels; availability and pricing are confirmed at quote time against an RFQ.","metaTitle":"MAX823TEUK Simple Reset/Power-On Reset, Active Low, 140ms","metaDescription":"MAX823TEUK supervisor IC: Simple Reset/Power-On Reset, active low push-pull output, 3.08V threshold, 140ms timeout, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.08V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.59","stockQuantity":0,"priceTiers":[{"qty":189,"price":"$1.59000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9fa6c6136a04a38394a95222693f778b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of MAX823TEUK?","answer":"The reset timeout is a minimum of 140 ms.
