MAX6321HPUK30CY

Supervisors Overview

The MAX6321HPUK30CY is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and processor activity in digital systems, featuring a fixed reset threshold voltage of 3.0V. The device operates within a supply voltage range up to 5.5V and includes manual reset functionality. It provides an active-low, open-drain reset output with a typical reset delay time of 200ms. The component supports a watchdog timer for system reliability and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply voltage levels and microprocessor activity
• Includes manual reset input for user-initiated system control
• Integrates a watchdog timer to detect software malfunctions
• Provides active-low open-drain reset output signal

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded controllers
• Watchdog timer implementation in digital systems

Supervisors Procurement Notes

Verify the specific suffix UK30CY against official datasheets to confirm the exact 3.0V threshold and package configuration. Ensure compatibility with existing board layouts for SOT-23-5 footprint. Confirm RoHS compliance status through manufacturer documentation before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed 3.0V threshold is required for single-voltage monitoring. Consider the integrated watchdog feature if software stability is a concern. Verify that the open-drain output type matches the downstream logic requirements without additional pull-up components.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices offer various combinations of reset outputs and features like watchdogs and manual resets. The MAX6321 variant specifically includes the watchdog timer capability alongside standard voltage supervision functions.

Supervisors Replacement Considerations

Check for other parts within the MAX6316–MAX6322 family that share the same 3.0V threshold but differ in output drive or timeout characteristics. Verify pinout compatibility before substituting with similar supervisory ICs from the same manufacturer.
