MAX6323BUT46-T

Supervisors Overview

The MAX6323BUT46-T is a microprocessor supervisory circuit from the MAX6323 family, manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and microprocessor activity in digital systems. The device features a windowed watchdog timer and manual reset capability. It operates within a supply voltage range up to 5.5V with a reset threshold of 4.63V. The output is push-pull, active low, and guaranteed valid down to VCC = +1.2V. It is housed in a SOT-23-6 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-specification system activity
• Provides manual reset functionality via an asserted low input
• Delivers a push-pull, active-low RESET output signal
• Ensures valid RESET output assertion down to a minimum supply voltage of 1.2V

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Watchdog timer implementation for system reliability

Supervisors Procurement Notes

Verify component status carefully as this specific part number may be obsolete or discontinued. Check current manufacturer documentation for lifecycle status. Ensure compatibility with existing design requirements if substituting. Confirm package integrity and pinout alignment during integration. Review datasheet revisions for any functional updates prior to procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for single-channel supervision. Consider the push-pull output type for direct driving capabilities. Evaluate the SOT-23-6 package constraints for PCB layout. Verify that the windowed watchdog feature meets the specific timing requirements of the target application compared to standard watchdog options.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 series of µP supervisory circuits. The 'H' or 'B' suffix variants typically denote different threshold voltages or temperature ranges within the same functional family. The MAX6323 specifically offers a push-pull output, whereas the MAX6324 variant provides an open-drain output. This series is designed for robust power management in embedded systems.

Supervisors Replacement Considerations

The MAX6323DUT46+ is a documented alternative within the same family offering similar supervisory functions. Verify electrical parameter equivalence, particularly the 4.63V threshold and push-pull output configuration. Ensure package compatibility remains consistent between the original and substitute parts.
