MAX6320PUK30BW-T

Supervisors Overview

The MAX6320PUK30BW-T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold voltage of 3.0V with an accuracy of 1.5%. The device provides a manual reset input and includes a watchdog timer for system monitoring. It utilizes an active-low, open-drain output stage and offers multiple timeout periods, including power-on reset delays ranging from 1ms to 1.12s and watchdog timeouts from 6.3ms to 25.6s. The component is housed in a compact 5-pin SOT-23 package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated configuration enables flexible designs through selectable reset thresholds and output stages
• Includes manual reset input and watchdog timer functionality for enhanced system robustness
• Available in factory-trimmed reset threshold voltages with specified accuracy

Supervisors Applications

• Monitoring power supplies in digital systems
• Supervising microprocessor activity in embedded applications
• Providing reset signals for battery-powered devices

Supervisors Procurement Notes

Verify the specific suffix 'BW' against official manufacturer documentation to confirm exact manufacturing lot or revision details, as standard datasheets may list generic variants like 'BU'. Ensure compatibility with required operating temperature ranges and package specifications before procurement. Cross-reference with authorized distributors to confirm current availability status.

Supervisors Selection Notes

Select this component when a fixed 3.0V reset threshold is required alongside manual reset and watchdog capabilities. Consider the 5-pin SOT-23 package for space-constrained designs. Evaluate the available timeout periods against system startup requirements. Verify that the open-drain output type aligns with the target logic interface.

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 features. They are widely used in industrial, consumer, and communication equipment requiring reliable power management.

Supervisors Replacement Considerations

Check for other parts within the MAX6320 series with different threshold voltages if the 3.0V setting is not suitable. Verify pinout compatibility with existing PCB layouts. Confirm that alternative components support the same watchdog and manual reset functionalities.
