MAX6308EUK00D3+

Supervisors Overview

The MAX6308EUK00D3+ is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed thresholds, specifically suited for tracking 5V and 3.3V rails in personal computer systems. The device asserts a system reset if any monitored supply falls outside its programmed threshold range. It includes four power-on reset timers and is engineered to ignore fast transients on monitored supplies. Packaged in a compact SOT23-5 format, it supports portable applications.

Supervisors Feature Summary

• Monitors more than one power supply simultaneously
• Asserts system reset when monitored supplies exceed programmed thresholds
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Monitoring 5V and 3.3V power supplies in personal computer systems
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific part number suffix against official Maxim Integrated documentation to confirm exact threshold voltages and package variations. Ensure compliance with RoHS standards if required by your application specifications. Cross-reference the datasheet revision date to ensure all electrical characteristics match your design requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required within a compact footprint. The fixed factory-programmed thresholds eliminate the need for external resistor networks, simplifying board layout. Consider the transient immunity feature for environments with noisy power lines or rapid load changes.

Supervisors Part Context

This device belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These CMOS supervisory circuits are optimized for monitoring dual power supplies, such as 5V and 3.3V, commonly found in PC architectures. The family shares common features like transient immunity and low current consumption.

Supervisors Replacement Considerations

Compatible substitutes within the same family include MAX6305 through MAX6313 variants, provided their specific factory-programmed threshold voltages match the required monitoring levels for the 5V and 3.3V rails.
