MAX6323EUT46-T

Supervisors Overview

The MAX6323EUT46-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 4.63 V. The device provides an active-low, push-pull output with a reset delay time of 180 ms. It includes a manual reset input and a windowed watchdog timer for system protection. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer capable of detecting both minimum and maximum timeout violations to ensure processor reliability.
• Includes a dedicated manual reset input pin allowing external systems to force a system reset independently of voltage conditions.
• Delivers a precise active-low push-pull output signal to reliably interface with various logic families without requiring additional pull-up components.

Supervisors Applications

• Microprocessor system supervision in industrial control environments
• Watchdog timer implementation in embedded computing devices
• Manual reset functionality in portable electronic equipment

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm electrical characteristics, as variations exist within the family. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply or end-of-life restrictions. Ensure the selected variant matches the required threshold voltage and package type for your design.

Supervisors Selection Notes

Select this component when a combination of voltage supervision, windowed watchdog monitoring, and manual reset capability is required in a small footprint. Consider the 4.63 V threshold and 180 ms delay against your system's power-up timing requirements. Evaluate the SOT-23-6 package constraints against your PCB layout space and thermal management needs.

Supervisors Part Context

This part belongs to the MAX6323 series of uP supervisory circuits designed for low-power applications. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its specific threshold voltage and integrated windowed watchdog feature set. The series targets applications requiring robust system monitoring in compact form factors.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative supervisory circuits based on matching threshold voltages, output types, and package dimensions before substitution.

Supervisors FAQ

What is the function of the windowed watchdog timer in this circuit?

The windowed watchdog timer monitors for both early and late interrupts, ensuring that the processor stays within acceptable timing bounds and triggering a reset if timeouts occur outside the specified window.

How does the manual reset input operate?

The manual reset input allows an external signal to actively drive the reset output low, forcing a system reset regardless of the monitored supply voltage level.
