MAX6354SVUK-T

Overview

The MAX6354SVUK-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent supply voltages and asserts active-low, push-pull reset outputs when any input drops below its preset threshold. The device features precision factory-set thresholds of 3.08V and 4.63V with an accuracy of 1.5%. It operates within a supply voltage range up to 5.5V and consumes only 20µA of quiescent current. The reset delay time is 180ms, and it includes a debounced manual reset input. The component is housed in a compact SOT-23-5 package and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Provides active-low, push-pull reset outputs referenced to specific supply rails
• Includes a debounced, TTL/CMOS-compatible manual-reset input
• Operates with low supply current for battery-powered applications

Applications

• Computers and intelligent instruments
• Controllers requiring multivoltage systems
• Portable and battery-powered equipment

Procurement Notes

Verify the exact suffix against official datasheets, as variations like SVUK-T may indicate specific thermal or packaging options not always detailed in generic summaries. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the ordering part number matches the required threshold voltages and package type before procurement.

Selection Notes

Select this component when monitoring two distinct voltage rails with fixed thresholds is required. The SOT-23-5 package suits space-constrained designs. Verify that the 180ms reset delay meets system timing requirements. Ensure the monitored voltages align with the available factory-set thresholds of 3.08V and 4.63V.

Part Context

This part belongs to the MAX6351–MAX6360 series of dual/triple-voltage µP supervisors. These devices improve system reliability by replacing discrete components with integrated monitoring solutions. The series offers various threshold combinations and package options, including 5-pin and 6-pin SOT23 variants, designed for high accuracy and low power consumption in industrial and consumer electronics.

Replacement Considerations

Check the MAX6353LTUK-T for similar dual-voltage monitoring with different output referencing. The MAX6356 series offers triple-voltage monitoring capabilities if a third rail needs supervision. Verify pinout compatibility and threshold voltage alignment when substituting.
