MAX6339OUT-T

Overview

The MAX6339OUT-T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent power supply rails simultaneously within a compact SOT-23-6 surface-mount package. The device provides active-low open-drain reset outputs for each monitored channel, ensuring reliable system initialization and protection against brown-out conditions. It operates with a maximum supply voltage of 5.5V and features a typical reset delay time of 200ms to prevent false triggering during power transitions.

Feature Summary

• Simultaneous monitoring of four distinct voltage inputs
• Active-low open-drain reset output configuration
• Compact SOT-23-6 surface-mount packaging

Applications

• Multi-rail embedded system power supervision
• Microprocessor board voltage monitoring
• Industrial control unit power integrity verification

Procurement Notes

Verify the specific suffix 'OUT' against official manufacturer documentation to confirm threshold configurations. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when simultaneous monitoring of four separate voltage rails is required in a space-constrained design. Consider the open-drain output type for level shifting capabilities. Verify that the 200ms reset delay aligns with the system's startup timing requirements and that the 5.5V maximum rating covers all monitored rail peaks.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It is designed for applications requiring comprehensive power management without consuming excessive board space. The series supports various threshold combinations to accommodate different logic families and power standards commonly found in consumer and industrial electronics.

Replacement Considerations

Consult the official cross-reference list for verified substitutes. Ensure any replacement maintains the quad-channel architecture and SOT-23-6 form factor. Verify electrical parameter equivalence for threshold voltages and reset delays.
