MAX6319MHUK46C+

Supervisors Overview

The MAX6319MHUK46C+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 4.6 V. The device provides a manual reset input and offers active high, active low, or push-pull output configurations. It consumes only 3 µA of operating current and includes a reset delay time of 1.4 ms. The component supports a single monitored input and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates manual reset functionality for system control
• Provides flexible output options including active high, active low, and push-pull modes
• Monitors power supply voltage with a fixed threshold

Supervisors Applications

• Microprocessor activity monitoring in digital systems
• Power supply supervision for embedded controllers
• System reset generation in industrial equipment

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as 'T' indicate tape-and-reel packaging while other suffixes may denote different thermal grades or lead finishes. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates mixed compliance levels across similar part numbers. Ensure the specific batch matches the required operating temperature range and package type before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for voltage supervision. Consider the 3 µA quiescent current for battery-sensitive applications. Verify that the SOT-23-5 package fits the board layout constraints. Check if the manual reset feature meets system requirements, noting that some variants in the family include watchdog timers which are absent in this specific configuration.

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 processor activity. The family offers various combinations of reset outputs and timeout periods. This specific model focuses on basic voltage supervision with manual reset capabilities, distinguishing it from variants that include watchdog timers or different threshold voltages.

Supervisors Replacement Considerations

Substitute parts must match the 4.6 V threshold and SOT-23-5 package. Verify compatibility of output drive strength and reset delay times. Cross-reference with other MAX6319 variants having identical electrical characteristics but different suffix codes for packaging or temperature grade adjustments.
