MAX6388XS39D5-T

Supervisors Overview

The MAX6388XS39D5-T is a dual-channel voltage supervisory circuit from the MAX6388XS series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5V and features an adjustable overvoltage threshold set at 4V. The device provides active-high, push-pull reset outputs with a fixed reset delay time of 2.4 seconds. It consumes only 7µA of supply current and functions reliably across an industrial temperature range of -40°C to +125°C. Packaged in a compact SC-70-4 surface-mount format, this component is designed for low-power microprocessor reset applications.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent power supply supervision
• Adjustable overvoltage threshold detection for flexible system protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance and lead-free specifications against specific order requirements. Check datasheet revisions for any functional updates. Ensure packaging details match design constraints. Validate thermal performance under actual load conditions before final integration.

Supervisors Selection Notes

Select this part when dual-channel supervision with adjustable overvoltage protection is required. Compare reset delay times against system startup requirements. Evaluate package size constraints against PCB layout limitations. Consider supply current impact on overall battery life. Verify compatibility with target logic voltage levels for the active-high output interface.

Supervisors Part Context

This component belongs to the MAX6388XS family of single and dual low-voltage, low-power microprocessor reset circuits. The series offers various threshold voltages and timeout delays to suit different application needs.
