MAX6306UK29D2+T

Supervisors Overview

The MAX6306UK29D2+T is a supervisory circuit designed for monitoring multiple power supplies. It features two monitored inputs with threshold voltages of 3.3V and 5V, housed in an SOT-23-5 package. The device provides an active low, open-drain reset output with a manual reset input capability. It operates within a supply voltage range up to 5.5V and includes a reset delay time of 28 ms. The component draws 8 uA of operating supply current and functions across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Monitors two distinct power supply inputs simultaneously
• Provides active low open-drain reset signal generation
• Includes manual reset input functionality for system control

Supervisors Applications

• Personal computer systems requiring dual voltage supervision
• Portable electronic devices needing low-power monitoring
• Embedded systems managing 3.3V and 5V rails

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check current availability as distribution channels may list limited stock or obsolete status. Ensure the SOT-23-5 footprint matches your PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two voltage rails is required. The open-drain output allows for wired-OR configurations. Consider the 28 ms reset delay for timing-sensitive applications. Verify that the 0°C to +70°C industrial temperature range meets your environmental specifications. Compare against single-input supervisors if only one rail requires monitoring.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits. These devices are engineered to ignore fast transients on monitored supplies. The series offers factory-programmed reset thresholds ranging from 2.5V to 5.0V. They are optimized for portable applications due to low supply current consumption and compact packaging.

Supervisors Replacement Considerations

Check for MAX6306 variants with different threshold suffixes if voltage levels differ. Single-input alternatives like MAX6861 may suffice if only one rail needs monitoring. Verify pinout compatibility with SOT-23-5 packages before substitution.
