MAX6339NUT+T

Overview

The MAX6339NUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four input voltages with thresholds of 2.78 V, 4.63 V, adjustable, and -4.63 V. The device features an active low open-drain output and a reset timeout of 140 ms minimum. It operates within a supply voltage range up to 5.5 V and functions across a temperature range of -40°C to +85°C. The component is housed in a SOT-23-6 package.

Feature Summary

• Monitors four distinct voltage inputs simultaneously
• Provides active low open-drain reset signal output
• Includes adjustable voltage threshold capability

Applications

• Embedded system power supervision
• Portable electronic device monitoring
• Industrial control unit voltage tracking

Procurement Notes

Verify the specific suffix NUT against official datasheets to confirm threshold configurations. Confirm RoHS compliance status through manufacturer documentation. Ensure the SOT-23-6 package matches design constraints. Check for obsolescence or lifecycle changes directly from Analog Devices. Validate thermal performance requirements against the specified operating temperature range.

Selection Notes

Select this component when simultaneous monitoring of four voltage rails is required in a compact form factor. The adjustable threshold option allows flexibility for non-standard voltage levels. Ensure the open-drain output interface is compatible with the downstream logic circuitry. Verify that the 140 ms reset delay meets system startup timing requirements.

Part Context

This part belongs to the MAX6339P series of voltage supervisors. It shares the quad-monitoring architecture with variants like MAX6339PUT+T but differs in specific threshold settings and package details. The series is designed for reliable power management in space-constrained applications requiring multi-rail supervision.

Replacement Considerations

MAX6339PUT+T offers similar quad monitoring capabilities in a SOT-23-6 package. Verify threshold voltage compatibility before substitution. Ensure pinout alignment between the NUT and PUT suffixes. Confirm identical electrical characteristics for critical parameters such as reset delay and operating temperature.
