MAX6313UK38D2-T

Supervisors Overview

The MAX6313UK38D2-T is a CMOS microprocessor supervisory circuit designed to monitor power supply voltages. It features a fixed reset threshold of 3.8V and an active-high, push-pull output type. The device operates with a maximum supply voltage of 5.5V and includes a reset delay time of 1.4ms. It functions within a temperature range of -40°C to +85°C and consumes 8µA of operating supply current. The component is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Provides system reset assertion when monitored supply falls below the programmed threshold
• Designed to ignore fast transients on any monitored supply line
• Guaranteed RESET valid down to VCC = 1V

Supervisors Applications

• Monitoring power supplies in portable applications
• Personal computer system power support
• Microprocessor (µP) supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the active-high output configuration, as suffixes often dictate electrical characteristics. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Ensure the SOT-23-5 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for systems powered by voltages near 3.8V. The low supply current makes it suitable for battery-operated devices. Verify that the 1.4ms reset delay meets the timing requirements of the target microprocessor or logic family during power-up sequences.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs from Maxim Integrated. These devices are engineered to monitor more than one power supply, making them ideal for complex systems requiring reliable supervision of multiple rails simultaneously.

Supervisors Replacement Considerations

Check for MAX6313 variants with different suffixes if active-low outputs or different thresholds are needed. Verify pinout compatibility with existing designs when substituting.
