MAX6388XS45D2-T

Supervisors Overview

The MAX6388XS45D2+T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5.5 V and features an adjustable overvoltage threshold with a nominal setting of 4.61 V. The device provides two monitored inputs with active high, push-pull outputs. Key electrical parameters include a fixed reset delay time of 40 ms and a typical operating supply current of 7 µA. It is housed in a compact SC-70-4 surface-mount package and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Dual-input voltage monitoring capability for independent power rail supervision
• Adjustable overvoltage detection threshold allowing customization for specific system requirements
• Low-power architecture designed for battery-operated applications with minimal quiescent current consumption
• Push-pull output stage providing robust drive capability without requiring external pull-up resistors

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing reliable voltage supervision for multiple logic rails
• Industrial control units operating in extended temperature environments
• Battery-powered equipment utilizing low-quiescent current supervisory circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications prior to integration. Ensure the ordering suffix matches the required tape-and-reel quantity. Validate that the adjustable threshold configuration aligns with the target application's voltage constraints. Check for any obsolescence notices or limited availability warnings associated with this specific part number.

Supervisors Selection Notes

Select this component when dual-channel supervision with adjustable overvoltage protection is required. The SC-70-4 package suits space-constrained designs. Consider the 7 µA supply current for energy-sensitive applications. Verify that the 40 ms reset delay meets system timing requirements. Ensure the input voltage range covers the maximum expected supply voltage of 5.5 V. Compare against single-channel alternatives if only one rail requires monitoring.

Supervisors Part Context

This part belongs to the MAX6388XS series of microprocessor supervisory circuits. The series offers various threshold voltages and timeout delays to accommodate different system architectures. The 'XS' designation typically indicates specific package and threshold variations within the broader MAX6388 family. These circuits are designed to replace discrete supervisor components, reducing board space and design complexity.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts maintain compatible pin configurations and electrical characteristics. Verify that alternative components support the same SC-70-4 package and temperature range. Confirm that the new part offers equivalent or superior performance metrics for the intended application.
