The operating temperature range of -40°C to 125°C covers industrial and automotive under-hood environments, making it suitable for motor drives, base stations, and engine control modules where the supervisor must keep working through thermal cycling. ## Active production, no end-of-life concern The MAX6389XS46D3 is listed as Active in production status. For BOM planning, this part can be specified into new designs without near-term obsolescence risk.","metaTitle":"MAX6389XS46D3 Multi-Voltage Supervisor, Active Low, SC-70-4","metaDescription":"MAX6389XS46D3 multi-voltage supervisor from Analog Devices.

After all monitored voltages rise above their thresholds, the reset output stays asserted for at least 140ms before releasing the system."},{"question":"Can MAX6389XS46D3 monitor 3.3V and 5V?","answer":"It can monitor a 5V rail directly using the fixed 4.63V threshold. The second channel is adjustable via external resistors, so it can be set to monitor a 3.3V rail or any other voltage down to about 1.2V."},{"question":"What is the closest pin-compatible alternative to MAX6389XS46D3?","answer":"Within the MAX6389 family, parts differ by the fixed threshold voltage and reset timeout. For a 4.63V fixed threshold with 140ms timeout, the MAX6389XS46D3 is the specific variant. A different fixed threshold (e.g., 3.08V) would require a different suffix in the MAX6389 series, but all share the same SC-70-4 footprint and pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6389XS46D3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6389XS46D3 when reusing this data.
