MAX6316LUK29AX+T

Supervisors Overview

The MAX6316LUK29AX+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in digital systems and features a fixed reset threshold voltage of 2.9V. The device operates within a supply voltage range up to 5.5V and consumes a typical quiescent current of 10µA. It provides an active-low, push-pull reset output with a standard reset delay time of 200ms. The component includes a manual reset input and a watchdog timer for system reliability. It is housed in a compact SOT-23-5 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Features a factory-trimmed fixed reset threshold voltage for precise monitoring
• Provides an active-low, push-pull reset output stage
• Designed to ignore fast negative transients on VCC

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Supervising microprocessor activity in industrial control units
• Ensuring system stability in automotive electronic modules

Supervisors Procurement Notes

Verify the exact suffix 'LUK29AX' to confirm the specific 2.9V threshold and package variant. Confirm RoHS compliance status as indicated in official documentation. Check current production lifecycle status, as availability may be limited or restricted. Ensure the ordering quantity meets any specified factory increment requirements if applicable.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required for voltage supervision. Consider the integrated watchdog and manual reset features for enhanced system robustness. Verify that the SOT-23-5 package fits the design constraints. Ensure the operating temperature range meets the application's environmental demands.

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 threshold voltages and timeout periods.

Supervisors Replacement Considerations

Other parts within the MAX6316–MAX6322 family may serve as substitutes if different threshold voltages or timeout periods are acceptable. Verify pin compatibility and electrical specifications before substitution.
