MAX6310UK40D2-T

Supervisors Overview

The MAX6310UK40D2-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with active low, push-pull outputs. The device provides a fixed reset threshold of 4.0V and operates within a supply voltage range up to 5.5V. It utilizes a SOT-23-5 package with dimensions of 2.9mm length, 1.63mm width, and 1.1mm height. The reset delay time is specified at 1.4ms, and the operating supply current is 8µA. It functions within a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Monitors two independent power supply inputs for system integrity
• Provides active low, push-pull reset output signals
• Immune to short transients on monitored supply lines
• Guaranteed valid reset output down to 1V supply voltage

Supervisors Applications

• Monitoring dual power rails in personal computer systems
• Supervising 5V and 3.3V supplies in portable electronics
• Microprocessor system reset generation

Supervisors Procurement Notes

Verify the specific suffix D2 corresponds to the 4.0V threshold configuration when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated for authenticity. Ensure the package matches the SOT-23-5 form factor. Check for lead-free compliance if required by assembly specifications. Validate the revision status against official datasheet documentation.

Supervisors Selection Notes

Select this component when dual-supervision capability is required for critical power rails. The low 8µA supply current makes it suitable for battery-operated devices. The small SOT-23-5 footprint aids in space-constrained PCB layouts. Ensure the 4.0V threshold aligns with the specific voltage rail being monitored. Consider the 1.4ms reset delay for timing-sensitive applications.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs. These devices are engineered for monitoring more than one power supply simultaneously. The series offers factory-programmed thresholds from 2.5V to 5.0V in 100mV increments. They are designed to ignore fast transients on any monitored supply line.

Supervisors Replacement Considerations

Substitutes within the MAX6305–MAX6313 family may be considered if threshold voltages match. Verify pin compatibility and package type before replacement. Cross-reference specific suffix codes to ensure identical electrical characteristics.
