MAX6324HUT29+T

Supervisors Overview

The MAX6324HUT29+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input with a fixed reset threshold of 2.93V. The device features an open-drain active-low reset output and includes a windowed watchdog timer with manual reset capability. It operates within a supply voltage range up to 5.5V, consuming 27µA of quiescent current. The component supports a reset delay of 180ms and maintains accuracy of 1.5%. It functions across a temperature range from -40°C to +125°C in a SOT-23-6 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for enhanced system reliability
• Includes a manual reset input for controlled system recovery
• Provides factory-trimmed reset thresholds with high accuracy
• Features an open-drain reset output compatible with various logic levels

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system supervision
• Industrial control systems
• Consumer electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'HUT29' to confirm the 2.93V threshold voltage before procurement. Ensure the open-drain output configuration aligns with the target circuit design. Confirm RoHS compliance status through official documentation. Check availability as distribution channels may indicate limited stock or end-of-life status for this specific variant.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. The open-drain output necessitates an external pull-up resistor. Consider the 1.5% accuracy requirement for precise voltage detection. The windowed watchdog function is suitable for detecting software hangs or abnormal processor activity. Evaluate the SOT-23-6 package size against board space constraints.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6324 variant specifically offers an open-drain reset output, distinguishing it from the push-pull MAX6323. The family provides multiple laser-trimmed threshold options ranging from 2.32V to 4.63V. These circuits are designed to monitor power supplies and microprocessor activity in digital systems.

Supervisors Replacement Considerations

MAX6324AUT29+T: Same series with potentially different temperature grade or packaging. MAX6324EUT46+T: Different threshold voltage (4.63V). MAX6323HUT29+T: Push-pull output instead of open-drain. Verify electrical compatibility and pinout alignment before substitution.
