MAX6324GUT46+

Supervisors Overview

The MAX6324GUT46+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 an open-drain RESET output asserted low when the supply voltage falls below the threshold or upon manual assertion. It operates within a supply voltage range of up to 5.5V and includes a reset delay time of 180ms. The component is housed in a SOT-23-6 package and supports surface-mount installation.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-specification system activity
• Provides manual reset capability via a dedicated MR input pin
• Features an open-drain active-low RESET output for flexible interfacing

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system supervision
• Watchdog timer implementation

Supervisors Procurement Notes

Verify the specific suffix 'G' against official datasheets, as standard listings typically utilize 'A', 'B', 'C', or 'E' grades. Confirm availability status with authorized distributors, as this specific part number may be subject to limited supply or discontinuation. Ensure the ordering information matches the required threshold voltage and package type before finalizing procurement.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision with integrated watchdog functionality. The open-drain output allows for wired-OR configurations. Consider the 180ms reset delay and 27uA operating current when designing for low-power or timing-sensitive environments. Verify that the 4.63V threshold aligns with the target supply rail requirements.

Supervisors Part Context

This component belongs to the MAX6324 series of µP supervisory circuits from Maxim Integrated. The series offers various laser-trimmed reset thresholds with high accuracy. The MAX6324 variant specifically features an open-drain output, distinguishing it from the push-pull MAX6323 counterpart. These devices are designed for reliable operation in harsh industrial and commercial environments.

Supervisors Replacement Considerations

Direct substitutes include MAX6324EUT46+T and MAX6324AUT29+T from the same manufacturer family. Cross-vendor replacements require matching the SOT-23-6 package, open-drain output configuration, and similar threshold voltages.
