MAX6321HPUK50DZ+

Supervisors Overview

The MAX6321HPUK50DZ+ is a microprocessor supervisory circuit in an SOT-753 package. It monitors a single power supply with a fixed 5.0V reset threshold. The device operates within a voltage range of 2.5V to 5.5V and features a minimum reset timeout period of 1.12 seconds. It provides open-drain or push-pull reset outputs and includes watchdog timer functionality. The component supports industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity
• Manual reset input capability for system control
• Flexible output configuration with open-drain or push-pull options

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in digital systems
• Embedded controller reset management

Supervisors Procurement Notes

Verify the specific suffix HPUK50DZ+ against the official datasheet to confirm the 5.0V threshold and SC-74A/SOT-753 package variant. Ensure the supplier provides documentation confirming the RoHS compliance status indicated by the '+' suffix. Cross-reference the manufacturer's current production status, as legacy Maxim Integrated parts may have limited availability or obsolescence notices.

Supervisors Selection Notes

Select this component when a fixed 5.0V reset threshold is required for 5V logic systems. The integrated watchdog and manual reset features reduce external component count compared to discrete solutions. Consider the SOT-753 package for space-constrained designs requiring both watchdog and manual reset capabilities in a small footprint.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These devices are designed to monitor power supplies and ensure reliable system startup and operation. The family offers various threshold voltages and timeout periods, with the MAX6321 specifically providing a 5.0V threshold and extended timeout characteristics suitable for complex digital systems.

Supervisors Replacement Considerations

The MAX6321HPUK50CX+T is a pin-compatible alternative within the same family offering similar supervisory functions.
