MAX6320PUK29DY+T

Supervisors Overview

The MAX6320PUK29DY+T is a fixed, single-channel power supply management circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a voltage range up to 5.5V and features a threshold voltage of 2.93V. The device utilizes an SOT-23-5 package with five pins. Key electrical parameters include a reset delay time of 200ms, an accuracy of 1.5%, and a maximum overvoltage threshold of 4.699V. It supports a minimum operating temperature of -40°C and a maximum of +125°C, with a typical working supply current of 10µA.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring microprocessor activity
• Manual reset input capability for system control
• Flexible open-drain or open-collector active-low reset output

Supervisors Applications

• Microprocessor supervisory circuits in digital systems
• Power supply monitoring for embedded controllers
• Watchdog timer implementation in industrial applications

Supervisors Procurement Notes

Verify the specific suffix 'DY' corresponds to the 2.93V threshold variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the SOT-23-5 package matches the design footprint. Cross-reference the manufacturer part number with Analog Devices or Maxim Integrated official catalogs to avoid counterfeit components. Check for any specific ordering increment requirements if purchasing directly from the factory rather than distributors.

Supervisors Selection Notes

Select this component when a fixed 2.93V reset threshold is required for single-supply monitoring. The integrated watchdog and manual reset features reduce external component count. Consider the 10µA supply current for low-power designs. The wide operating temperature range suits harsh environments. Verify that the open-drain output type aligns with the target logic level requirements of the connected processor.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity. The family offers various combinations of reset outputs, watchdog timers, and manual reset inputs. They are available in multiple factory-trimmed reset threshold voltages ranging from 2.5V to 5V. The MAX6320 variant specifically includes both watchdog and manual reset functionalities.

Supervisors Replacement Considerations

Other parts in the MAX6316–MAX6322 family may serve as substitutes if different reset thresholds or timeout periods are acceptable. Verify pin compatibility and package size (SOT-23-5) before substitution. Ensure the replacement part supports the same watchdog and manual reset features if these are critical to the design.
