MAX6323AUT29-T

Supervisors Overview

The MAX6323AUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies and microprocessor activity in digital systems, featuring a windowed watchdog timer and manual reset capability. The device operates within a supply voltage range of 1.2V to 5.5V and includes a laser-trimmed reset threshold of 2.93V with ±2.5% accuracy. It provides an active-low push-pull RESET output and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect system malfunctions outside expected operational windows.
• Includes a manual reset input for external control of the reset state.
• Delivers a guaranteed valid RESET output signal down to a supply voltage of 1.2V.
• Features a push-pull output structure for robust drive capability.

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Microprocessor activity supervision in industrial controllers
• System reset management in battery-powered devices

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets, as tape-and-reel packaging options may vary. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability for specific variants can fluctuate based on production cycles.

Supervisors Selection Notes

Select this component when a windowed watchdog timer and manual reset are required alongside low-voltage operation. Ensure the 2.93V threshold aligns with the monitored rail and that the push-pull output suits the interface requirements compared to open-drain alternatives.

Supervisors Part Context

This part belongs to the MAX6323 series of uP supervisory circuits designed for monitoring power rails and processor activity. It distinguishes itself through integrated windowed watchdog functionality and manual reset inputs, offering higher integration than basic voltage supervisors while maintaining low power consumption suitable for portable applications.

Supervisors Replacement Considerations

Consider the MAX6323DUT46+T for similar functionality with a different reset threshold (4.63V). Verify pinout compatibility and electrical characteristics before substitution.
