MAX6322HPUK29A+T

Supervisors Overview

The MAX6322HPUK29A+T 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 2.9V with an accuracy of 1%. The device operates within a supply voltage range of 1.25V to 5.5V and consumes low quiescent current. It provides a push/pull or open-drain reset output and includes manual reset and watchdog timer functionalities. The component is housed in a compact SOT-23-5 package and supports operation across an extended temperature range.

Supervisors Feature Summary

• Integrates manual reset input for system control
• Includes built-in watchdog timer for processor monitoring
• Offers factory-trimmed reset threshold voltages
• Provides multiple reset output configurations

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered embedded systems

• Industrial control systems with watchdog requirements

Supervisors Procurement Notes

Verify the specific suffix 'HPUK29A' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with existing board layouts for the SOT-23-5 footprint. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.9V reset threshold is required alongside manual reset and watchdog capabilities. Consider the SOT-23-5 package size constraints and the need for low quiescent current operation. Evaluate if the available timeout periods and output drive strengths meet the target system's timing and load requirements compared to other variants in the MAX63xx series.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of general-purpose supervisory circuits. These devices are characterized by their combination of voltage monitoring, manual reset inputs, and watchdog timers in small packages. The family offers various threshold voltages and timeout options to suit different digital system architectures.

Supervisors Replacement Considerations

Direct substitutes within the same family include MAX6322HPUK28A+T (2.8V threshold) and MAX6322HPUK30A+T (3.0V threshold), provided the reset voltage tolerance aligns with system requirements. Verify pinout compatibility and electrical specifications before substitution.
