The surface-mount footprint matches the standard SOT-23-8 land pattern; no special pad geometry required. Rated for -40°C to 85°C ambient, it covers industrial control, telecom base stations, and outdoor equipment enclosures where the internal temperature stays below 85°C. ## Lifecycle and sourcing — active, no LTB pressure Listed as Active with ROHS3 compliance.","metaTitle":"MAX6366LKA46+T Battery Backup Circuit, 4.63V Threshold","metaDescription":"Maxim MAX6366LKA46+T battery backup supervisory IC.

The 4.63V threshold is designed for 5V nominal supplies — it asserts reset when the rail drops to approximately 4.63V, which is within the typical undervoltage window for 5V logic. It monitors a single voltage input."},{"question":"What is the closest pin-compatible alternative to MAX6366LKA46+T?","answer":"Within the MAX6366 family, the threshold voltage is the differentiating factor. The MAX6366LKA29+T uses a 2.93V threshold for 3.3V rails, and the MAX6366LKA31+T uses a 3.08V threshold. All share the same SOT-23-8 package, active-low push-pull output, and 150ms timeout — the only difference is the monitored voltage level. For a 5V rail, the 4.63V variant is the correct choice."},{"question":"Is MAX6366LKA46+T compatible with 3.3V systems?","answer":"No. The 4.63V threshold is too high for a 3.3V rail — the reset would assert continuously. For 3.3V systems, use a threshold variant such as the MAX6366LKA29+T (2.93V) or MAX6366LKA31+T (3.08V)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6366LKA46T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6366LKA46T when reusing this data.
