MAX6354LTUK+T

Overview

The MAX6354LTUK+T is a dual-voltage supervisory circuit from the MAX6353L series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input supply voltages with factory-set thresholds of 3.08 V and 4.63 V. The device features active low push-pull outputs and a manual reset input. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 1.5%. The reset delay time is 180 ms, and the quiescent supply current is 20 µA. It functions reliably between -40°C and +85°C in an SOT-23-5 package.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Provides debounced TTL/CMOS-compatible manual-reset input
• Ensures RESET validity down to 1.0 V on monitored inputs
• Offers power-supply transient immunity without external components

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability before integration. Check for obsolescence notices as availability may be restricted. Ensure storage conditions align with moisture sensitivity level requirements to prevent package damage during soldering processes.

Selection Notes

Select this supervisor when precise monitoring of two specific voltage rails is required without external resistor dividers. The fixed threshold values eliminate calibration needs. Consider the 20 µA current consumption for battery-operated designs. Verify that the active low push-pull output drives the target microprocessor reset pin correctly within the system logic levels.

Part Context

This component belongs to the MAX6353L family of microprocessor supervisory circuits. These devices improve system reliability by replacing discrete monitoring components. The MAX6354 variant specifically addresses dual-voltage applications, offering a compact solution for embedded systems requiring simultaneous supervision of distinct power domains.

Replacement Considerations

Check MAX6352MSUK+T for similar dual-input supervision with open-drain outputs. Review MAX6350ESA+T if a single-channel high-precision reference is needed instead of supervision.
