MAX6307UK27D4-T

Supervisors Overview

The MAX6307UK27D4-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range up to 5.5V and features a fixed reset threshold of 2.7V. The device provides an active low, open-drain output and includes a manual reset input. It is housed in a compact SOT-23-5 package with dimensions of 2.9mm length and 1.1mm height. The component supports surface mount installation and functions within a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Provides active low open-drain reset signal output
• Includes manual reset input capability
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits
• Voltage supervision in embedded systems

Supervisors Procurement Notes

Verify the specific suffix D4 against official Analog Devices documentation to confirm the exact factory-programmed threshold voltage and pin configuration. Ensure compatibility with the required operating temperature range and package type before integration. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Supervisors Selection Notes

Select this component when monitoring multiple voltage rails is required within a small footprint. The fixed 2.7V threshold suits applications where this specific level triggers the necessary reset condition. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the manual reset feature aligns with the system's control logic requirements.

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 specifically engineered to assert a system reset if any monitored supply falls outside its programmed threshold. The series is characterized by low supply current and transient immunity, making it suitable for portable and personal computer applications.
