MAX6306UK44D2+

Supervisors Overview

The MAX6306UK44D2+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 4.4V and an active-low open-drain output. The device includes a manual reset input and operates within a supply voltage range up to 5.5V. It draws 8µA of operating current and provides a reset delay time of 28ms. The component is housed in a compact SOT-23-5 surface-mount package and supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Provides active-low open-drain reset signal generation
• Includes manual reset input capability for user control

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Embedded systems requiring multi-supervision
• Industrial control circuits with multiple power domains

Supervisors Procurement Notes

Verify the exact suffix (e.g., D2, D4) against official datasheets to confirm threshold voltage and delay specifications. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure RoHS compliance documentation matches the specific manufacturing batch requirements for your assembly process.

Supervisors Selection Notes

Select this part when fixed threshold supervision at 4.4V is required without programmable adjustment. Compare reset delay times against other MAX6306 variants if timing sensitivity is critical. Verify that the SOT-23-5 package fits the board layout constraints and that the open-drain output interface is compatible with the downstream logic levels.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered for applications requiring reliable power supply monitoring across various digital systems.

Supervisors Replacement Considerations

Check for other MAX6306 variants with different suffixes (e.g., UK29, UK31) if the 4.4V threshold does not match the target rail voltage. Verify pinout compatibility before substituting with other supervisory ICs from the same family.
