MAX6307UK31D1-T

Supervisors Overview

The MAX6307UK31D1-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3V and 5V. The device provides an active low, open-drain output and includes manual reset functionality. It operates within a supply voltage range up to 5.5V, consumes 8µA of operating current, and offers a reset delay time of 200ms. The component is housed in a SOT-23-5 package and supports surface-mount installation.

Supervisors Feature Summary

• Monitors dual power supply inputs for system integrity
• Provides active low open-drain reset signal output
• Includes manual reset input capability
• Operates with low supply current consumption

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring small package size
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm the exact threshold configuration and revision status. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm that the open-drain output type aligns with the downstream logic requirements of the application design.

Supervisors Selection Notes

Select this component when dual-input voltage supervision is required with fixed thresholds. The open-drain output necessitates an external pull-up resistor. Consider the 200ms reset delay duration relative to system startup timing requirements. Verify that the 8µA quiescent current meets the power budget constraints for the intended portable or embedded application environment.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered to ignore fast transients on monitored supplies, making them suitable for robust system reset generation in digital electronics where power stability is critical.

Supervisors Replacement Considerations

Consult the official datasheet for cross-reference options within the MAX6305–MAX6313 family. Verify pinout compatibility and electrical parameter equivalence before substituting with other multi-input supervisory circuits from different manufacturers.
