MAX6323CUT46+

Supervisors Overview

The MAX6323CUT46+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring power supplies and system activity in digital applications. It operates within a supply voltage range of 1.2V to 5.5V and features a laser-trimmed reset threshold of 4.63V with ±2.5% accuracy. The device includes a windowed watchdog timer and manual reset functionality, housed in a compact SOT-23-6 surface-mount package. It supports active low push-pull output and maintains operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated windowed watchdog timer monitors system activity outside expected operational windows
• Manual reset input allows external assertion of the reset signal independent of voltage levels
• Guaranteed valid reset output down to 1.2V supply voltage for reliable low-power operation

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Ensuring microprocessor activity integrity via watchdog functions
• Providing reset signals for battery-powered devices requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check datasheet revisions for any updates to electrical characteristics or pin configurations before integration into final designs.

Supervisors Selection Notes

Select this part when precise 4.63V threshold detection is required alongside watchdog supervision. Consider the SOT-23-6 footprint for space-constrained layouts. Ensure the active low push-pull output matches the target system's input requirements without additional buffering.

Supervisors Part Context

This component belongs to the MAX6323 series of uP supervisory circuits, which offer various threshold options and output types. It shares architectural similarities with other members like the MAX6323DUT46+ but differs in specific threshold trimming and packaging variants within the same product family.

Supervisors Replacement Considerations

Direct substitutes include other MAX6323 variants with matching 4.63V thresholds and SOT-23-6 packages, such as MAX6323HUT46+T, provided functional compatibility with existing circuitry is verified.
