MAX6354SYUK+

Overview

The MAX6354SYUK+T is a dual-voltage supervisory circuit manufactured by Analog Devices (Maxim Integrated). It monitors two independent voltage rails with thresholds of 3.08 V and 4.63 V. The device features an active-low, push-pull output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and maintains accuracy within 1.5%. The component draws 20 µA of quiescent current and includes an 180 ms reset delay timer. It is housed in a compact SOT-23-5 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel voltage supervision for independent power rail monitoring
• Manual reset capability for system control flexibility
• Low-power operation suitable for battery-supplied applications

Applications

• Portable electronic devices requiring multi-rail power management
• Industrial control systems needing voltage supervision
• Embedded systems with strict power consumption constraints

Procurement Notes

Verify the specific suffix 'SY' against official documentation to confirm threshold voltages and pinout compatibility. Confirm RoHS compliance status through the manufacturer's datasheet. Check current availability as distribution channels may list limited stock or end-of-life status. Ensure the ordering part number matches the required package type and thermal rating for your specific application environment.

Selection Notes

Select this component when dual voltage monitoring is required in a minimal footprint. The low quiescent current makes it ideal for portable designs. Verify that the 3.08 V and 4.63 V thresholds align with your system's critical voltage levels. Consider the manual reset feature if external user intervention is needed for system recovery. Ensure the operating temperature range meets your environmental requirements.

Part Context

This part belongs to the MAX6353L series of supervisory circuits. It shares functional similarities with other Maxim Integrated voltage supervisors but offers specific dual-threshold capabilities. The series is designed for cost-sensitive applications requiring reliable power management without complex external components.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX635x family. Verify equivalent threshold voltages and output configurations. Ensure compatible package types such as SOT-23-5 are available from alternative sources.
