MAX6323HUT46+T

Supervisors Overview

The MAX6323HUT46+T is a microprocessor supervisory circuit from the MAX6323 series, manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a fixed threshold of 4.63 V and offers ±1.5% accuracy. The device features an active low push-pull output, a manual reset input, and a windowed watchdog timer. It operates within a supply voltage range up to 5.5 V and maintains functionality down to 1.2 V. Key electrical parameters include a reset delay of 180 ms, a quiescent current of 27 uA, and an overvoltage threshold of 4.75 V. It supports a power dissipation of 696 mW and functions across a temperature range of -40°C to +125°C in a SOT-23-6 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect system malfunctions outside expected operational windows.
• Includes a manual reset input for initiating system resets on demand.
• Provides high-accuracy voltage monitoring with laser-trimmed thresholds.

Supervisors Applications

• Monitoring power supplies in digital systems
• Ensuring microprocessor activity stability
• Embedded system supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance and lead times directly with suppliers as stock levels fluctuate. Ensure the specific suffix matches design requirements before ordering.

Supervisors Selection Notes

Select this part for applications requiring precise voltage monitoring with integrated watchdog capabilities. Consider the 4.63 V threshold and 180 ms reset delay against system timing requirements. Evaluate the SOT-23-6 package size and operating temperature range for environmental compatibility.

Supervisors Part Context

This component belongs to the MAX6323 family of uP supervisory circuits designed for low-power applications. It complements other Maxim Integrated monitoring solutions by offering combined voltage supervision and watchdog functionality in a compact surface-mount package suitable for space-constrained designs.

Supervisors Replacement Considerations

Consult official documentation for direct substitutes. Verify pinout compatibility and threshold voltage alignment when considering alternative supervisory circuits from the same manufacturer or competitors.

Supervisors FAQ

What is the function of the windowed watchdog timer?

It monitors system activity and asserts a reset if the processor fails to toggle the watchdog input within a specified time window, indicating a potential malfunction.

How does the manual reset input operate?

Asserting the manual reset input low forces the RESET output low, allowing external triggers to initiate a system reset regardless of voltage conditions.
