MAX6321HPUK46CY+T

Supervisors Overview

The MAX6321HPUK46CY+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input with a fixed threshold of 4.6 V and features an active-low, open-drain reset output. The device includes manual reset functionality and a watchdog timer with a 200 ms timeout period. Operating within a supply voltage range up to 5.5 V, it draws 10 uA of quiescent current. The component is housed in a compact SOT-23-5 surface-mount package and supports an industrial temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset capability via dedicated input
• Features low quiescent current consumption for power efficiency

Supervisors Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Industrial control systems requiring watchdog protection

Supervisors Procurement Notes

Verify availability status as this part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance and lead times through authorized distributors. Ensure ordering suffixes match required package and temperature specifications. Cross-reference datasheet revisions for any functional updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required alongside integrated watchdog and manual reset features. Consider the SOT-23-5 package for space-constrained designs. Verify that the open-drain output configuration aligns with the target system's pull-up requirements. Compare against similar MAX63xx series parts if adjustable thresholds or different output types are needed.

Supervisors Part Context

This part belongs to the MAX6321 series of uPower supervisors designed for embedded applications. It shares architectural similarities with other MAX63xx devices but is distinguished by its specific 4.6 V threshold and combination of watchdog and manual reset functions. The series targets cost-sensitive, low-power environments where reliable system monitoring is critical.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX63xx family with matching thresholds. Verify that substitute parts support the same watchdog timeout and manual reset logic. Ensure thermal and electrical ratings meet original design specifications.
