MAX6385XS32D4-T

Supervisors Overview

The MAX6385XS32D4-T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8V to 5V and features a factory-set reset threshold of 3.2V. The device utilizes an SC-70-4 surface-mount package and provides an active-high, push-pull reset output. It includes a manual reset input but lacks a watchdog timer or battery backup switch. The reset timeout delay is specified at 280ms minimum. Operating temperatures range from -40°C to +125°C with a typical quiescent current of 7µA.

Supervisors Feature Summary

• Provides active-high push-pull reset output for reliable logic interfacing
• Includes manual reset input for system control flexibility
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Portable electronic device voltage supervision
• Industrial control system reset generation

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and RoHS compliance upon receipt. Cross-reference datasheet revision dates to ensure parameter accuracy. Validate manufacturing lot codes against official Analog Devices records. Inspect for physical damage before integration into final assemblies.

Supervisors Selection Notes

Select this variant when an active-high output is required instead of the standard active-low configuration found in other MAX6385 series members. Ensure the 3.2V threshold aligns with the target supply rail. Verify that the SC-70-4 footprint matches the PCB layout constraints. Consider the 280ms timeout duration relative to microprocessor startup requirements.

Supervisors Part Context

This component belongs to the MAX6385XS family of low-power reset circuits. It shares architectural similarities with the MAX6381–MAX6390 series but differs in output polarity and specific threshold settings. The 'XS' designation indicates specific threshold and timeout combinations within the broader uPower reset circuit portfolio designed for space-constrained applications.

Supervisors Replacement Considerations

Direct substitutes include MAX6385XS32D4+ for non-tape versions. Other MAX6385 variants with matching thresholds may serve as alternatives if output polarity adjustments are acceptable in the design.
