MAX6320PUK43CY/V+T

Supervisors Overview

The MAX6320PUK43CY/V+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.3V with an accuracy of 1.5%. The device provides an active-low open-drain reset output and includes manual reset functionality. It operates within a supply voltage range up to 5.5V and supports a watchdog timer. The component is housed in a compact SOT-23-5 package and functions reliably across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrated configuration enables flexible designs through selectable reset outputs
• Includes watchdog timer and manual reset features for system reliability
• Factory-trimmed reset threshold voltages ensure precise monitoring

Supervisors Applications

• Microprocessor (μP) supervisory circuits
• Power supply management systems
• Digital system monitoring

Supervisors Procurement Notes

Verify the exact suffix 'V' against official Maxim Integrated documentation, as standard listings typically use 'CY'. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability may vary by region. Ensure the ordering increment requirements match your procurement volume, as specific factory versions may have distinct minimum order quantities compared to standard catalog items.

Supervisors Selection Notes

Select this part when a fixed 4.3V threshold is required for single-supply monitoring. The open-drain output suits interfaces requiring external pull-ups. Consider the SOT-23-5 footprint for space-constrained PCB layouts. Verify that the 1.5% accuracy meets the system's noise margin requirements. Ensure the manual reset input aligns with the user interface design for emergency system recovery.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are characterized by their miniature SOT-23 packaging and integrated watchdog timers. The family offers various combinations of reset outputs and timeout periods, catering to diverse digital system protection needs. The MAX6320 variant specifically integrates manual reset capability alongside the watchdog function.

Supervisors Replacement Considerations

Check for MAX6320 variants with different threshold suffixes if the 4.3V level is adjustable. Verify pinout compatibility with other SOT-23-5 supervisors. Cross-reference with MAX6340 series if watchdog functionality is not required.
