MAX6354TWUK-T

Overview

The MAX6354TWUK-T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors multiple power-supply voltages to improve system reliability. The device features precision factory-set reset thresholds for +2.5V, +3.0V, +3.3V, and +5V supplies. It operates with a supply current of 20µA and provides a minimum 100ms power-on reset pulse width. The RESET output remains valid down to VCC5 = 1V or VCC3 = 1V. It includes a debounced manual-reset input and is available in small SOT-23 packages.

Feature Summary

• Precision monitoring of multiple standard voltage rails including +2.5V, +3.0V, +3.3V, and +5V
• Factory-set power-supply reset thresholds eliminate the need for external components in dual-voltage systems
• Low power consumption with a typical supply current of 20µA
• Debounced TTL/CMOS-compatible manual-reset input for user-initiated control

Applications

• Computers
• Intelligent instruments
• Controllers
• Multivoltage systems
• Portable/battery-powered equipment

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet, as variations exist within the MAX6354 family. Confirm package type and temperature range specifications match the design requirements. Cross-reference the part number with the latest Analog Devices documentation to ensure compatibility with current manufacturing standards and pinout definitions before procurement.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage rails is required from a single IC. It is suitable for designs needing guaranteed reset validity at low supply voltages (down to 1V). Consider the 20µA quiescent current for battery-operated applications. Ensure the specific threshold voltages provided by the TWUK variant align with the target power rails.

Part Context

The MAX6354 belongs to the Maxim Integrated MAX6351–MAX6360 series of microprocessor supervisors. This family is designed to replace separate ICs or discrete components for improved accuracy and reliability. The devices are characterized for operation over extended temperature ranges and offer various package options including SOT-23.

Replacement Considerations

Check the MAX6354LTUK+T and MAX6354UKZD0+T for potential alternatives within the same family. Verify that threshold voltages and package types are compatible before substitution.
