MAX6339MUT-T

Overview

The MAX6339MUT-T is a quad voltage supervisor integrated circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors four independent supply rails and provides active-low reset signals via open-drain or open-collector outputs when voltages fall below specified thresholds. The device operates within a supply voltage range of 1V to 5.5V and features a minimum reset timeout of 140ms. Thresholds include fixed options such as 2.63V and 4.38V, alongside adjustable inputs. It functions reliably across an industrial temperature range of -40°C to +85°C in a compact SOT-23-6 surface-mount package.

Feature Summary

• Monitors four independent voltage channels simultaneously
• Provides active-low reset signals with open-drain or open-collector outputs
• Includes adjustable threshold inputs for flexible voltage monitoring
• Operates within a wide supply voltage range up to 5.5V

Applications

• Multi-rail power system supervision in embedded systems
• Voltage monitoring for microprocessor and memory circuits
• Industrial control board power integrity verification

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet, as variations exist within the MAX6339 family. Confirm that the specific part number matches the required threshold settings and output type. Check component status, as some variants may be discontinued or subject to supply restrictions. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required in a space-constrained design. The adjustable threshold capability allows customization for non-standard supply levels. Consider the open-drain output structure for compatibility with various logic families. Verify that the 140ms minimum reset delay meets the system startup timing requirements.

Part Context

This component belongs to the MAX6339P series of quad voltage supervisors. It is designed for applications requiring comprehensive power management without external components. The SOT-23-6 package offers a small form factor suitable for portable and dense electronic assemblies. It complements other Maxim Integrated supervisory solutions by providing multi-channel oversight in a single IC.
