MAX6323BUT29-T

Supervisors Overview

The MAX6323BUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors system power supplies and features a windowed watchdog timer with manual reset capability. The device operates within a supply voltage range of 1.2V to 5.5V, utilizing an SOT-23-6 package. Key electrical parameters include a reset threshold voltage of 2.93V, a reset delay time of 180ms, and a typical operating current of 27µA. The output type is active low push-pull, ensuring valid reset signals down to VCC = 1.2V.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect abnormal system activity outside expected operational windows.
• Provides manual reset functionality via an asserted low input signal for controlled system restarts.
• Delivers a push-pull reset output that remains asserted low during power-down or threshold violations.

Supervisors Applications

• Monitoring digital system power supplies in embedded controllers
• Ensuring microprocessor activity integrity through watchdog supervision
• Providing manual reset inputs for industrial control systems

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the 'BUT' designation aligns with the 2.93V threshold variant. Check current availability status as some distributors may list limited stock or end-of-life conditions for this specific Maxim Integrated part number.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. Consider the push-pull output requirement versus open-drain alternatives like the MAX6324 series. Ensure the 180ms reset delay and 27µA current consumption meet the system's power and timing constraints.

Supervisors Part Context

This part belongs to the MAX6323F/H/B series of uP supervisory circuits. It shares the same functional architecture as other variants but differs in laser-trimmed reset thresholds ranging from 2.32V to 4.63V. The MAX6323 family distinguishes itself with windowed watchdog capabilities compared to basic supervisors.

Supervisors Replacement Considerations

MAX6323BUT29+T: Identical part with lead-free RoHS compliance confirmation; verify if the '-T' suffix implies specific reel handling differences.

Supervisors FAQ

What is the difference between MAX6323 and MAX6324 output types?

The MAX6323 provides a push-pull (active low) reset output, whereas the MAX6324 offers an open-drain reset output. Both share similar threshold and watchdog functionalities.

Does the MAX6323 support battery backup switching?

No, the MAX6323 does not include a battery backup switch feature. It is designed strictly for power supply monitoring and watchdog supervision without automatic switchover capabilities.
