MAX6357SYUT+T

Overview

The MAX6357SYUT+T is a supervisory circuit designed for microprocessor systems, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a reset threshold of 2.93V with an active-low push-pull output. The device includes a fixed reset delay time of 180ms and consumes a typical operating supply current of 20µA. It is housed in a compact SOT-23-6 package and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Provides precise voltage supervision with a factory-set reset threshold
• Features active-low push-pull output driver for direct logic interface
• Includes fixed reset delay timer to ensure stable power-up sequencing

Applications

• Microprocessor system monitoring
• Battery-powered equipment supervision
• Portable electronic devices requiring low standby current

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package marking and date codes against official documentation. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference ordering information carefully as suffixes may indicate specific testing or packaging variations.

Selection Notes

Select this component when a fixed threshold supervisor with push-pull output is required. Consider the 20µA quiescent current for battery efficiency. Verify that the 180ms delay aligns with system power-up requirements. Ensure the 5.5V maximum rating accommodates peak supply voltages without exceeding limits.

Part Context

This part belongs to the MAX6357S series of supervisory circuits. It shares functional similarities with other members like the MAX6355L but differs in output type and specific threshold settings. The series is designed for cost-effective voltage monitoring in space-constrained applications using small outline transistor packages.

Replacement Considerations

Direct substitutes include MAX6357SYUT+T variants with identical electrical characteristics. Check pinout compatibility before substitution. Verify threshold voltage tolerance matches application requirements. Confirm package dimensions fit existing PCB footprints.
