MAX6322HPUK29A

Supervisors Overview

The MAX6322HPUK29A is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 2.93V with no adjustability. The device provides manual reset functionality via an external input. It operates within a supply voltage range of 1.0V to 5.5V and supports an active-low push/pull or open-drain reset output. The component is qualified for automotive applications under AEC-Q100 standards and functions reliably across an extended temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supply voltage levels to ensure system stability
• Includes manual reset input for user-initiated system recovery
• Automotive-grade qualification for reliable operation in harsh environments

Supervisors Applications

• Microprocessor power supply supervision in digital systems
• Automotive electronic control units requiring AEC-Q100 compliance
• Embedded systems needing manual reset capabilities

Supervisors Procurement Notes

Verify the specific suffix 'UK29A' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm that the fixed threshold meets the design requirements without need for adjustment. Check current production status and availability through authorized distributors.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for monitoring low-voltage rails. The inclusion of a manual reset input distinguishes it from variants lacking this feature. Consider the AEC-Q100 qualification if the application involves automotive environments. Compare against other MAX63xx variants to ensure the specific timeout period and output type match the system design constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are engineered to monitor power supplies and microprocessor activity. The family offers various combinations of reset outputs and features like watchdog timers. The MAX6322 specifically includes manual reset functionality, providing flexibility for system control beyond automatic power-on reset generation.

Supervisors Replacement Considerations

Direct substitutes within the MAX63xx family include parts with identical thresholds and manual reset features, such as MAX6322HPUK29D4+T. Verify that replacement parts maintain the same AEC-Q100 qualification and operating temperature range. Ensure the pinout and package dimensions remain compatible with the existing design.
