MAX6339BUT+

Overview

The MAX6339BUT+ is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent input voltages with thresholds of 4.5 V, 1.26 V, 3.15 V, and 4.75 V. The device features an active low, open-drain output and a reset delay time of 140 ms minimum. It operates within a supply voltage range of 1 V to 5.5 V and consumes 55 µA of quiescent current. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Monitors up to four distinct power rails simultaneously
• Provides active low open-drain reset signal output
• Operates with low quiescent current consumption
• Suitable for industrial temperature environments

Applications

• Embedded microprocessor systems
• Motor control applications
• Networking equipment signal processing

Procurement Notes

Verify the specific suffix 'BUT' against official datasheets to confirm threshold configurations. Confirm RoHS compliance status as required by project specifications. Check product lifecycle status for availability constraints. Ensure package type matches SOT-23-6 requirements. Validate operating temperature range suitability for the target environment.

Selection Notes

Select this component when simultaneous monitoring of four voltage levels is required. Consider the 140 ms reset timeout for system stability needs. Evaluate the 55 µA current draw against battery life requirements. Ensure the 1 V to 5.5 V input range covers all monitored rails. Verify compatibility with open-drain logic interfaces.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory ICs but offers specific threshold combinations. The series is designed for embedded systems requiring reliable power management. It complements broader power management portfolios from Analog Devices.
