MAX6323HUT29+T

Supervisors Overview

The MAX6323HUT29+T is a microprocessor supervisory circuit in a six-pin SOT-23 package. It monitors a single voltage input with a fixed threshold of 2.93V and offers a push-pull active-low output. Key features include a windowed watchdog timer, manual reset capability, and a 180ms reset delay. The device operates from -40°C to +125°C with a maximum supply voltage of 5.5V and consumes 27µA. Valid RESET output is guaranteed down to VCC = +1.2V.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for monitoring system activity outside expected operational windows.
• Provides manual reset functionality via an asserted low MR input.
• Delivers a push-pull active-low RESET output signal.

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor (µP) activity supervision
• Embedded controller reset management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required threshold and package variant. Check current lifecycle status as availability may be limited. Ensure compliance with RoHS standards if applicable to your assembly process. Validate datasheet revisions against your design requirements.

Supervisors Selection Notes

Select this part when a fixed 2.93V threshold is required alongside integrated watchdog and manual reset functions. Compare against MAX6324 variants if an open-drain output is preferred instead of push-pull. Consider the operating temperature range and supply voltage limits relative to your system's power rails. Verify that the SOT-23-6 footprint fits your PCB layout constraints.

Supervisors Part Context

This component belongs to the MAX6323F/H series of µP supervisory circuits. These devices are designed to monitor power supplies and ensure reliable system startup and operation. The family typically includes variations with different thresholds and output types, sharing core functionalities like watchdog timers and manual resets within compact packages.

Supervisors Replacement Considerations

MAX6323DUT46+T shares similar supervisory features but differs in threshold voltage and potentially manufacturing source. Verify electrical compatibility before substitution. Other MAX6323 variants may offer different output types or thresholds; confirm functional equivalence for your specific application needs.
