MAX6339OUT-T REEL

Overview

The MAX6339OUT-T REEL is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent power supply rails and provides reset signals when voltages deviate from specified thresholds. The device operates within a supply voltage range of 2.5 V to 5.5 V and features an active low, open-drain output. It includes a fixed 200 ms reset delay timer and maintains accuracy within 5%. The component is available in SOT-23-6 packages and supports operation across temperatures from -40°C to +85°C.

Feature Summary

• Monitors four distinct voltage inputs simultaneously for system integrity
• Provides active low open-drain reset signal upon threshold violation
• Integrates a fixed 200 ms timeout delay for stable power-up sequencing

Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for microprocessor and FPGA boards
• Industrial control unit power management

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold selection and package type. Confirm RoHS compliance status and manufacturing origin through authorized distributors. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when simultaneous monitoring of four voltage rails is required without manual reset functionality. Ensure the operating temperature range meets environmental specifications. Verify that the 200 ms delay aligns with system startup timing requirements.

Part Context

This part belongs to the MAX6339P series of voltage supervisors designed for compact applications. It integrates multiple monitoring channels into a single small footprint, reducing board space compared to discrete solutions. The series focuses on reliable power management for digital logic circuits.

Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives. Verify threshold voltage compatibility and package dimensions before substituting.
