MAX6305UK00D4-T

Supervisors Overview

The MAX6305UK00D4-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with adjustable threshold voltages, supporting common levels such as 3.3 V and 5 V. The device provides an active low, open-drain reset output with a reset delay time of 1570 ms. It operates within a maximum supply voltage of 5.5 V and consumes a low operating supply current of 8 uA. Packaged in a compact SOT-23-5 format, it lacks manual reset, watchdog timer, and battery backup switching functions.

Supervisors Feature Summary

• Monitors more than one power supply for system integrity
• Features adjustable overvoltage thresholds for flexible configuration
• 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

Supervisors Procurement Notes

Verify the specific suffix D4 against the official datasheet to confirm the exact factory-programmed threshold values and temperature range. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Cross-reference the manufacturer part number with the distributor listing to avoid obsolete or discontinued variants.

Supervisors Selection Notes

Select this component when dual-supervision of distinct voltage rails is required without manual intervention. The open-drain output allows for wired-OR configurations with other logic devices. Consider the 1570 ms reset delay duration relative to the system's startup requirements. Verify that the 8 uA quiescent current meets the power budget constraints for the intended application environment.

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 the programmed threshold. The series is characterized by its ability to handle multiple input channels within a small SOT-23-5 package, making it suitable for space-constrained designs.

Supervisors Replacement Considerations

Check for MAX6305EUK00D2+T or MAX6305UK00D3+T as potential functional equivalents within the same series. Verify that substitute parts maintain the same SOT-23-5 package and open-drain output characteristics. Ensure the replacement offers compatible threshold voltage settings and reset delay times.
