MAX6323FUT29-T

Supervisors Overview

The MAX6323FUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and microprocessor activity in digital systems, featuring a windowed watchdog timer and manual reset capability. The device operates within a supply voltage range of +1.2V to +5.5V with a maximum threshold of 5.5V. It utilizes an SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +125°C. Key electrical parameters include a fixed reset threshold voltage of 2.93V, a reset delay time of 280ms, and a quiescent current of 27µA. The output type is active low push-pull.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect system malfunctions outside expected operational windows.
• Provides manual reset functionality via a dedicated input pin for external control.
• Delivers a valid RESET output signal even at low supply voltages down to +1.2V.
• Features laser-trimmed reset thresholds ensuring high accuracy without requiring external components.

Supervisors Applications

• Microprocessor (µP) supervisory circuits
• Digital system power supply monitoring
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as Maxim was acquired by ADI. Check RoHS compliance status for the specific batch. Ensure the component matches the SOT-23-6 footprint requirements for your PCB design.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. The push-pull output drives loads directly without needing pull-up resistors. Consider the 27µA quiescent current for battery-sensitive designs. Verify that the 280ms reset delay aligns with your system's startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The 'F' suffix typically denotes specific threshold options within the series. The MAX6323 variant specifically provides a push-pull output, distinguishing it from the open-drain MAX6324. These devices are designed for compact applications due to their small SOT-23-6 package.

Supervisors Replacement Considerations

MAX6323HUT29+ offers similar supervision with potentially different accuracy specifications. MAX6323DUT29+ is another variant within the same functional family. Cross-reference datasheets for exact threshold tolerances and output drive capabilities before substitution.
