MAX6339DUT+T

Overview

The MAX6339DUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a surface-mount SOT-23-6 package. It monitors four distinct power supply rails with threshold voltages of -5 V, 3.3 V, 5 V, and an adjustable setting. The device features active low open-drain outputs and a fixed reset delay time of 200 ms. It operates within a supply voltage range up to 5.5 V and maintains an accuracy of 5%. The component supports industrial temperature ranges from -40°C to +85°C and consumes 55 µA of operating supply current.

Feature Summary

• Monitors four independent voltage inputs simultaneously for system integrity
• Provides active low open-drain reset signals for logic interfacing
• Includes an adjustable threshold channel for custom voltage monitoring
• Operates with low quiescent current suitable for power-sensitive designs

Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for microprocessor reset sequences
• Industrial control board power integrity verification
• Communication equipment power rail validation

Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct threshold settings and package type. Confirm RoHS compliance status and lead times with authorized distributors as availability varies. Cross-reference the specific part number variant to match required voltage thresholds and output characteristics before procurement.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required in a compact footprint. The adjustable threshold option provides flexibility for non-standard rails. Ensure the active low open-drain output compatibility matches the downstream logic requirements. Verify that the 200 ms reset delay aligns with the system startup timing constraints.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors designed for applications requiring comprehensive power management. It complements single and dual-channel variants by offering multi-rail oversight in a small SOT-23-6 package. The series targets cost-sensitive and space-constrained electronic designs needing reliable voltage supervision without complex external components.
