MAX6321HPUK30CY-T

Supervisors Overview

The MAX6321HPUK30CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.7V to 5.5V and features a fixed reset threshold voltage of 3.0V with an accuracy of 1%. The device provides a push-pull reset output and includes manual reset functionality. It is housed in a compact SOT-23-5 surface-mount package and supports an extended industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity
• Manual reset input for system control flexibility
• Push-pull reset output configuration

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset management
• Industrial control board protection

Supervisors Procurement Notes

Verify the exact suffix CY against official Analog Devices documentation to confirm temperature grade and packaging specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference the part number with current manufacturer lifecycle status to confirm availability and obsolescence risks before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.0V threshold is required for digital logic levels. The inclusion of a watchdog timer distinguishes it from basic supervisors. Consider the push-pull output capability if driving loads directly without external pull-up resistors is necessary. Verify that the 5.5V maximum operating voltage aligns with the target system's power rail.

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 combinations of reset thresholds, timeout periods, and output types to suit different digital system requirements.

Supervisors Replacement Considerations

Compatible substitutes include other members of the MAX6316–MAX6322 family with matching threshold voltages and output configurations. Verify pinout compatibility and electrical characteristics before substitution.
