MAX6319LHUK46C-T

Supervisors Overview

The MAX6319LHUK46C-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 with an accuracy of 1.5%. The device provides a manual reset input and utilizes a push-pull output configuration. 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 manual reset input for system control
• Provides active high or low push-pull reset outputs
• Features factory-trimmed fixed reset threshold voltages

Supervisors Applications

• Monitoring power supplies in digital systems
• Supervising microprocessor activity
• Ensuring reliable startup sequences

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as '+T' variants typically denote lead-free construction. Check current availability as distribution channels may list limited stock or end-of-life statuses for this specific part number.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-supply monitoring. Ensure the application does not require a watchdog timer, as this variant lacks that feature. Verify that the SOT-23-5 package fits the board layout constraints and that the 1.5% accuracy meets the design specifications.

Supervisors Part Context

This part belongs to the MAX6319 family of uP supervisors. Unlike the MAX6316 series which includes watchdog timers, the MAX6319 focuses on voltage supervision with manual reset capabilities. The 'LH' designation typically indicates specific threshold and package variations within the broader product line.

Supervisors Replacement Considerations

Consider MAX6319LHUK46C+ for lead-free versions. For devices requiring watchdog functionality, evaluate the MAX6316 series instead.
