MAX6339MUT

Overview

The MAX6339MUT is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent supply voltages and provides active low open-drain reset outputs when thresholds are exceeded. The device operates within a supply voltage range of up to 5.5 V with a typical quiescent current of 55 uA. It features a fixed reset delay time of 200 ms and maintains an accuracy of 5%. The component is housed in a SOT-23-6 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Monitors four distinct power supply rails simultaneously for system integrity
• Provides active low open-drain reset signals upon threshold violation
• Ensures stable operation with a fixed 200 ms reset delay timer

Applications

• Multi-rail embedded system power supervision
• Industrial control unit voltage monitoring
• Telecommunications equipment power management

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage selection, as variants exist within the MAX6339 family. Confirm availability status through authorized distributors, as lead times may vary. Ensure the SOT-23-6 footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when simultaneous monitoring of four separate voltage lines is required in space-constrained designs. The SOT-23-6 package offers a compact solution compared to larger alternatives. Consider the 5% accuracy specification and 200 ms delay to ensure compatibility with the target system's startup and fault response timing requirements.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It shares functional similarities with other Maxim integrated circuits designed for power management but is distinguished by its four-channel capability and specific SOT-23-6 packaging. It serves as a dedicated solution for complex multi-voltage architectures requiring reliable fault detection.
