It asserts a common active-low reset output (open-drain) whenever any monitored voltage falls below its threshold. The factory-programmed thresholds are 1.67 V, 3.08 V, and 4.63 V, with a fourth adjustable input for a custom trip point. This part is designed for systems that need to sequence or supervise multiple power domains — think FPGA core + I/O banks, mixed-signal boards with analog and digital supplies, or telecom line cards with multiple voltage planes. ## Thresholds and reset behaviour The three fixed thresholds are 1.67 V, 3.08 V, and 4.63 V. The adjustable input sets a fourth threshold with an external resistor divider. ## Lifecycle and sourcing The MAX6709DUB is listed as Active on Maxim's product status. No last-time-buy or end-of-life notice is in effect. It is RoHS non-compliant per the original release — if your BOM requires RoHS compliance, verify the lead-free suffix variant (MAX6709DUB+ or similar) with your distributor.","metaTitle":"MAX6709DUB Multi-Voltage Supervisor, Quad Monitor","metaDescription":"MAX6709DUB multi-voltage supervisor monitors four rails with thresholds 1.67V, 3.08V, 4.63V, Adj.

The ADM708 typically has a fixed threshold (e.g., 2.93 V for 3 V systems) and a push-pull or open-drain output. The MAX6709DUB offers three fixed thresholds plus an adjustable input, making it suitable for multi-rail supervision in a single package. For single-rail monitoring, the ADM708 is a simpler, lower-cost choice; for quad monitoring, the MAX6709DUB consolidates what would otherwise require four separate supervisors."},{"question":"Is MAX6709DUB compatible with 3.3V systems?","answer":"Yes. One of the fixed thresholds is 3.08 V, which is the standard undervoltage trip point for a 3.3 V rail (typically 2.93–3.08 V). The open-drain output can be pulled up to 3.3 V or any other voltage within the absolute maximum ratings, making it directly compatible with 3.3 V logic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6709DUB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6709DUB when reusing this data.
