MAX6354RVUK-T

Overview

The MAX6354RVUK-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent power-supply voltages and asserts active-low, push-pull reset outputs when any input drops below its preset threshold. The device features 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 functions reliably over an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors two independent power-supply voltages simultaneously
• Provides active-low, push-pull reset outputs referenced to VCC2
• Includes debounced manual-reset input compatible with TTL/CMOS logic
• Operates with low supply current for battery-powered applications

Applications

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

Procurement Notes

Verify the specific suffix RVUK against official Analog Devices documentation to confirm exact threshold values and package type. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure RoHS compliance matches project requirements. Cross-reference pinout configurations with the latest datasheet revision before PCB layout finalization.

Selection Notes

Select this component when precise monitoring of two distinct voltage rails is required without external components. The fixed thresholds simplify design compared to adjustable supervisors. Consider the 180ms reset delay and 20µA current consumption for system timing and power budget constraints. Verify that the SOT-23-5 package fits the mechanical constraints of the target application.

Part Context

This part belongs to the MAX6351–MAX6360 family of dual/triple-voltage µP supervisors. These circuits improve system reliability by replacing discrete monitoring components. 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 embedded systems.

Replacement Considerations

Check for MAX6354LTUK+T or MAX6354UTUK+T if different threshold voltages are acceptable. Verify pin compatibility with other MAX635x variants before substitution.
