MAX6320PUK46BY/V+T

Supervisors Overview

The MAX6320PUK46BY/V+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors one voltage input with a threshold of 4.63V and an overvoltage threshold of 4.699V. The device features an active-low open-drain reset output, a manual reset input, and a watchdog timer. Reset delay time is 1.4ms. Operating supply voltage maximum is 5.5V. Quiescent current is 10uA. Accuracy is 1.5%. Temperature range is -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity
• Manual reset input capability for system control
• Open-drain reset output configuration
• Compact 5-pin SOT-23 surface-mount packaging

Supervisors Applications

• Microprocessor power supply supervision
• Digital system reset management
• Watchdog timer implementation in embedded systems

Supervisors Procurement Notes

Verify the specific suffix BY against the official datasheet to confirm the exact reset threshold voltage and timeout characteristics. Ensure the V+T designation matches the required tape-and-reel packaging format. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Supervisors Selection Notes

Select this component when an open-drain reset output is required for wired-OR configurations or level shifting. The integrated watchdog function simplifies design by eliminating external timing components. Verify that the 4.63V threshold aligns with the monitored rail voltage requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of μP supervisory circuits from Maxim Integrated (now Analog Devices). The family offers various combinations of reset outputs, watchdog timers, and manual reset inputs in miniature packages.

Supervisors Replacement Considerations

Cross-reference with other MAX6320 variants having identical pinouts and electrical specifications. Verify functional compatibility regarding watchdog timeout periods and reset delay times before substitution.
