MAX6382XR44D5

Supervisors Overview

The MAX6382XR44D5 is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.4V. The device provides an active-high, push-pull reset output with a typical timeout delay of 280ms. It consumes low quiescent current and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SC-70-3 surface-mount case, it offers high accuracy for precise power monitoring applications.

Supervisors Feature Summary

• Monitors single power-supply voltage with factory-set reset threshold
• Provides active-high push-pull reset output signal
• Ensures reliable system recovery via minimum reset timeout period
• Operates efficiently with ultra-low supply current consumption

Supervisors Applications

• Portable battery-powered equipment requiring low-power supervision
• Wireless communication modules and handheld devices
• Embedded systems needing precise voltage monitoring
• Industrial control units operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix D5 against official datasheets to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and lead-free specifications prior to ordering. Check manufacturer lifecycle status as availability may be restricted or subject to limited production runs. Ensure compatibility with existing PCB footprint and thermal requirements.

Supervisors Selection Notes

Select this component when a fixed 4.4V threshold is required for single-rail monitoring. Choose over adjustable variants if design stability and reduced external component count are priorities. Consider the SC-70-3 package size for space-constrained layouts. Verify that the active-high output logic aligns with the target microprocessor reset input requirements.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor power supplies ranging from 1.8V to 5.0V. The series is characterized by minimal supply current and multiple available reset timeout delays, ensuring robust protection for sensitive digital logic and memory components in various electronic systems.

Supervisors Replacement Considerations

Cross-reference with other MAX6382 variants sharing the same SC-70-3 package but different threshold voltages if voltage levels differ. Verify functional equivalence with MAX6380 or MAX6381 series parts if pinout and output polarity match. Always validate electrical parameters against the latest manufacturer documentation before substitution.
