MAX6324GUT29+T

Supervisors Overview

The MAX6324GUT29+T is a microprocessor supervisory circuit from the MAX6323/MAX6324 family, manufactured by Analog Devices (Maxim Integrated). It monitors power supplies and microprocessor activity in digital systems. The device features a windowed watchdog timer and manual reset input. It provides an active-low open-drain RESET output, which asserts when VCC falls below the fixed 2.93V threshold or upon manual assertion. Valid RESET output is guaranteed down to VCC = +1.2V. The circuit operates with a supply voltage range up to 5.5V and includes a 180ms reset delay. It is housed in a compact SOT-23-6 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-window microprocessor activity
• Provides active-low open-drain reset output for flexible system interfacing
• Includes manual reset input for external control of the reset state
• Guarantees valid reset output operation at low supply voltages down to 1.2V

Supervisors Applications

• Microprocessor (µP) power supply monitoring in digital systems
• Watchdog timer implementation for system stability verification
• Manual reset circuit integration for user-initiated system restarts

Supervisors Procurement Notes

Verify the exact suffix '+T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated by the '+' suffix. Check current manufacturing status as related variants may be obsolete. Ensure the open-drain output type matches the target design requirements rather than push-pull alternatives.

Supervisors Selection Notes

Select this component when an open-drain reset output is required for wired-OR configurations or level shifting. The fixed 2.93V threshold suits applications where this specific voltage level aligns with the monitored rail's minimum operating requirement. Consider the 180ms delay for appropriate startup timing relative to the load.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 µP supervisory circuit family. The MAX6323 variant offers a push-pull output, while the MAX6324 series, including this model, provides an open-drain output. These circuits are designed for robust power management in embedded systems requiring reliable reset generation and watchdog functionality.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: MAX6323HUT29+ (Push-pull output variant), MAX6324GUT29+T (Same electrical specs, different reel quantity/packaging indicator).
