MAX6323CUT29+T

Supervisors Overview

The MAX6323CUT29+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and processor activity in digital systems, featuring a windowed watchdog timer and manual reset input. The device provides a push-pull active-low RESET output, asserted when VCC falls below the threshold or upon manual assertion. It operates within a supply voltage range of 1.2V to 5.5V, with a fixed reset threshold of 2.93V. Key electrical parameters include a maximum operating current of 27µA, a reset delay time of 280ms, and an accuracy of ±2.5%. The component is housed in a compact SOT-23-6 surface-mount package.

Supervisors Feature Summary

• Integrated windowed watchdog timer for monitoring processor activity outside expected operational windows
• Manual reset input allows external assertion of the reset signal independent of voltage levels
• Push-pull active-low RESET output ensures valid logic states down to VCC = +1.2V
• Laser-trimmed fixed reset threshold voltage with high manufacturing accuracy

Supervisors Applications

• Microprocessor system power supply supervision
• Digital embedded systems requiring watchdog functionality
• Battery-powered devices needing low standby current
• Industrial control units operating in wide temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'CUT' against official manufacturer documentation, as standard Maxim part numbers typically utilize 'FUT', 'HUT', or 'AUT'. Confirm RoHS compliance status (+) and ensure the 2.93V threshold matches design requirements. Check availability status, as this series may be subject to limited supply or discontinuation notices from Analog Devices.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required alongside integrated watchdog and manual reset capabilities. Consider the SOT-23-6 package size for space-constrained designs. Ensure the application voltage remains above 1.2V for valid RESET output. Compare against MAX6323 variants with different thresholds if voltage levels differ.

Supervisors Part Context

The MAX6323 belongs to the Maxim Integrated µP Supervisory Circuits family, designed for monitoring power supplies and processor activity. This series includes variants with different reset thresholds, output types (push-pull vs. open-drain), and timeout periods. The MAX6323 specifically denotes the push-pull output configuration, distinguishing it from the MAX6324 open-drain version.

Supervisors Replacement Considerations

MAX6323FUT29+T: Same function, different suffix indicating specific trim/version. MAX6323HUT29+T: Higher accuracy variant (±1.5%). MAX6323DUT29+T: Alternative package/suffix variation. Verify pinout and threshold voltage compatibility before substitution.
