MAX6319LHUK29B+T

Supervisors Overview

The MAX6319LHUK29B+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.93 V for monitoring a single input channel. The device utilizes an SOT-23-5 surface-mount package and provides push-pull, totem pole reset outputs that are active high or active low. It includes a manual reset function but lacks a watchdog timer or battery backup switch. The reset timeout period has a minimum duration of 20 ms. Operating temperatures span from -40°C to +125°C with an accuracy of 1.5%.

Supervisors Feature Summary

• Provides precise voltage supervision with factory-trimmed threshold accuracy
• Integrates manual reset capability for system control flexibility
• Supports bidirectional reset output configurations via push-pull design

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status at major retailers. Confirm RoHS compliance and lead-free pin plating specifications against current datasheet revisions. Validate package marking codes and lot traceability records prior to integration into production assemblies to ensure long-term reliability and regulatory adherence.

Supervisors Selection Notes

Select this part when a fixed 2.93 V threshold is required for single-channel monitoring without watchdog functionality. Consider the manual reset feature for applications needing external intervention capabilities. Ensure the operating temperature range meets environmental requirements and verify compatibility with available reset timeout periods.
