MAX6388XS27D5-T

Supervisors Overview

The MAX6388XS27D5-T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two power-supply inputs within the +1.8V to +5.0V range, featuring an adjustable threshold voltage of 2.7V with an overvoltage threshold of 2.7V. The device provides an active-high, push-pull reset output with a fixed reset delay time of 2.4 seconds. It operates on a supply voltage up to 5.5V, consumes 7µA of supply current, and offers ±2.5% accuracy. The component is housed in an SC-70-4 package and functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel voltage supervision for monitoring multiple power rails simultaneously
• Active-high push-pull reset output configuration
• Adjustable reset threshold voltage capability
• Extended industrial operating temperature range

Supervisors Applications

• Embedded systems requiring dual power rail monitoring
• Portable electronic devices with low-power constraints
• Industrial control units needing reliable voltage supervision
• Communication equipment power management circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and lead-free packaging specifications prior to integration. Ensure the specific suffix matches design requirements as variants may differ in electrical characteristics. Validate that the SC-70-4 footprint aligns with existing PCB layouts. Check for obsolescence notices or lifecycle changes from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with an active-high output interface. The adjustable threshold feature allows customization for specific supply levels within the 1.8V to 5V range. Consider the 2.4-second timeout period against system startup requirements. The low 7µA quiescent current makes it suitable for battery-operated applications. Verify that the SC-70-4 package size fits the mechanical constraints of the target enclosure.

Supervisors Part Context

This part belongs to the MAX6388XS series of low-voltage, low-power microprocessor reset circuits. The series is designed for applications requiring precise voltage supervision in compact form factors. Analog Devices acquired Maxim Integrated, integrating these products into their portfolio. The MAX6388 variant specifically supports dual-channel monitoring, distinguishing it from single-channel counterparts in the broader MAX6381–MAX6390 family.
