MAX6324HUT46

Supervisors Overview

The MAX6324HUT46 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 (min/max) watchdog timer and manual reset capability. The device operates within a supply voltage range of 1.2V to 5.5V with a reset threshold of 4.63V. It utilizes an SOT-23-6 surface-mount package and draws a typical operating current of 27µA. The circuit provides an active-low open-drain RESET output and functions reliably across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect system malfunctions outside expected operational windows
• Includes a manual reset input for external control of the reset state
• Provides valid reset output signals down to a low supply voltage of 1.2V
• Features laser-trimmed reset thresholds for precise voltage supervision

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system activity supervision
• Windowed watchdog timer implementation
• Manual reset circuit integration

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain device integrity during assembly processes.

Supervisors Selection Notes

Select this component when a windowed watchdog function is required alongside voltage supervision. The open-drain output suits applications needing wired-OR configurations. Verify that the 4.63V threshold aligns with the target supply rail. Consider the SOT-23-6 footprint constraints against available board space.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6324 variant specifically features an open-drain output, distinguishing it from the push-pull MAX6323. Both share identical functional blocks including the windowed watchdog and manual reset inputs, differing primarily in output stage architecture.

Supervisors Replacement Considerations

MAX6323HUT46+T serves as a functional substitute with identical parameters except for the push-pull output configuration instead of open-drain.
