MAX6388XS34D5-T

Supervisors Overview

The MAX6388XS34D5-T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent power-supply voltages within a range of +1.8V to +5.0V while consuming only 7µA of supply current. The device features an adjustable reset threshold voltage centered at 3.4V with a tolerance of ±2.5%. It provides active-high, push-pull outputs and includes a fixed reset delay time of 560ms. The component operates reliably across an extended temperature range from -40°C to +125°C and is housed in a compact UDFN-6 surface-mount package.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent power rails
• Ultra-low quiescent current consumption for battery efficiency
• Adjustable reset threshold voltage for flexible system integration
• Active-high push-pull output configuration

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing efficient voltage monitoring
• Industrial equipment operating in extreme temperature environments
• Embedded controllers requiring reliable power-fail detection

Supervisors Procurement Notes

Verify the specific suffix D5 indicates the UDFN-6 package variant distinct from other pinout configurations. Confirm the XS series denotes adjustable thresholds rather than fixed factory-set values. Ensure the part number matches the exact manufacturer designation to avoid compatibility issues with existing board layouts.

Supervisors Selection Notes

Select this component when dual-voltage supervision is required in space-constrained designs. The adjustable threshold allows customization for specific rail voltages without changing part numbers. Consider the 560ms delay for applications tolerant of slower reset assertions. Verify thermal requirements align with the specified operating temperature range.

Supervisors Part Context

This part belongs to the MAX6388 family of low-voltage, low-power reset circuits. It shares functional similarities with single-channel variants but adds dual-input monitoring. The series is designed for applications where power integrity is critical and size constraints limit the use of larger packages.
