It asserts a reset output (active low, open drain) whenever either monitored voltage drops below its threshold, and holds reset for a minimum of 140 ms after all rails return to tolerance. This part is designed for systems that need to sequence or protect separate core and I/O voltages—think FPGA/CPLD boards, DSP cards, or mixed-signal modules where both supplies must be valid before the processor is released. ## What the 140 ms reset timeout buys you A 140 ms minimum reset timeout is deliberately long enough to let the power supply and on-chip decoupling settle after a brownout or power-up event. In practice, this means the downstream processor, FPGA, or ASIC sees a clean, glitch-free release—no partial boot, no metastable register state. For designs that already have a separate watchdog timer, this supervisor serves as the voltage monitor only; the open-drain output can be wire-ORed with other reset sources on the same pull-up line. ## Lifecycle and sourcing posture The MAX6831ZWUT+T carries an active product status per the manufacturer, with ROHS3 compliance.","metaTitle":"MAX6831ZWUT+T Multi-Voltage Supervisor, Active Low, SOT-23-6","metaDescription":"MAX6831ZWUT+T multi-voltage supervisor monitors two thresholds (1.67V, 2.313V) with 140ms min reset timeout.

It asserts an active-low, open-drain reset with a minimum timeout of 140 ms. It operates from -40°C to 125°C and comes in a SOT-23-6 (SOT-6) surface-mount package."},{"question":"Does MAX6831ZWUT+T have an open drain output?","answer":"Yes, the reset output is open drain (or open collector), which allows multiple supervisors to share a common reset line via an external pull-up resistor."},{"question":"What is the reset timeout of MAX6831ZWUT+T?","answer":"The reset timeout is a minimum of 140 ms. This ensures the monitored supplies have stabilized before the processor is released from reset."},{"question":"Can MAX6831ZWUT+T monitor multiple voltages?","answer":"Yes, it monitors two voltages simultaneously, with thresholds set at 1.67 V and 2.313 V. This makes it suitable for dual-rail systems such as FPGA boards with separate core and I/O supplies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6831ZWUTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6831ZWUTT when reusing this data.
