It is a surface-mount device. The push-pull output means the reset pin connects directly to the processor reset input without an external pull-up. ## Lifecycle and compliance note There is no last-time-buy or obsolescence risk for new designs. However, the part is RoHS non-compliant, which restricts its use in products destined for RoHS-regulated regions unless an exemption applies.","metaTitle":"MAX823MEUK Simple Reset/Power-On Reset IC, 4.38V Threshold","metaDescription":"MAX823MEUK supervisor IC with 4.38V reset threshold, active-low push-pull output, 140ms timeout. -40°C to 125°C range.

They share the same SOT-23-5 package and pinout, so a board designed for one can accept the other, but the threshold must match the supply rail being monitored. For a 3.3V rail, use the SEUK; for a 5V rail, use the MEUK."},{"question":"What is MAX823MEUK's listed type on this component line?","answer":"The listed type is Simple Reset/Power-On Reset. It is a basic voltage supervisor that asserts a reset when the supply drops below the threshold and releases it after a fixed timeout once the supply recovers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX823MEUK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX823MEUK when reusing this data.
