MAX6323DUT29-T

Supervisors Overview

The MAX6323DUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed to monitor power supplies and system activity in digital applications. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 2.93V with ±2.5% accuracy. The device includes a windowed watchdog timer and manual reset input, utilizing an active-low push-pull output. Packaged in a compact SOT-23-6 surface-mount format, it supports operation across an extended temperature range from -40°C to +125°C while consuming only 27µA of quiescent current.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for monitoring expected system activity windows
• Provides manual reset capability via dedicated input pin
• Delivers active-low push-pull reset output signal
• Ensures valid reset assertion down to minimum supply voltage of 1.2V

Supervisors Applications

• Microprocessor power supply supervision
• Digital system activity monitoring
• Embedded controller reset management
• Battery-powered device power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm package marking and date codes align with production specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly. Cross-reference ordering suffixes carefully as they may indicate specific tape-and-reel configurations or regional variants that do not alter electrical function.

Supervisors Selection Notes

Select this component when precise low-voltage supervision is required alongside watchdog functionality. The fixed 2.93V threshold suits systems operating near 3.3V rails. Consider the SOT-23-6 footprint for space-constrained designs. Evaluate the 27µA quiescent current against battery life requirements. Verify thermal performance within the specified -40°C to +125°C operational range for industrial or automotive environments.

Supervisors Part Context

Part of the MAX6323 series offering various reset thresholds and output types. The 'D' suffix typically denotes push-pull output configuration, distinguishing it from open-drain variants like the MAX6324. This family provides laser-trimmed accuracy for reliable supervision without external calibration components.

Supervisors Replacement Considerations

Direct functional substitutes include other MAX6323 variants with compatible reset thresholds and output types. Verify pinout compatibility and electrical parameters such as quiescent current and reset delay times before substitution.
