MAX6306UK46D3-T

Supervisors Overview

The MAX6306UK46D3-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 4.63V. The device provides an active-low, open-drain output with a manual reset input capability. It consumes low supply current of 8µA and includes a reset delay time of 1.4ms. Packaged in a compact SOT-23-5 format, it supports surface-mount installation.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Features manual reset input for user-initiated control
• Provides active-low open-drain reset signal output

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low power consumption
• Embedded systems needing reliable power supervision

Supervisors Procurement Notes

Verify the exact suffix designation as datasheets typically list this variant as MAX6306UK46D3+T. Confirm RoHS compliance status and lead-free certification with the manufacturer or authorized distributor before finalizing procurement specifications to ensure regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for specific logic levels. Ensure the application does not demand watchdog timer functionality, as this model lacks that feature. Verify that the SOT-23-5 package dimensions fit the PCB layout constraints and that the 8µA quiescent current meets the system's power budget requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These circuits are engineered to assert a system reset if any monitored supply falls outside its programmed threshold. The series is optimized for ignoring fast transients on monitored supplies, making it suitable for noisy environments common in computing applications.

Supervisors Replacement Considerations

Check for MAX6306UK46D3+T as the standard RoHS-compliant equivalent. Other variants in the MAX6306 series may serve as substitutes if different threshold voltages are acceptable.
