MAX6320PUK46BX+

Supervisors Overview

The MAX6320PUK46BX+ is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity in digital systems. It features a fixed reset threshold voltage of 4.5V with 1.5% accuracy. The device provides an active-low open-drain reset output and includes integrated watchdog timer and manual reset capabilities. Operating within a supply range up to 5.5V, it ensures system reliability through precise voltage monitoring and configurable timeout periods.

Supervisors Feature Summary

• Integrated configuration supports flexible design implementations
• Factory-trimmed reset threshold voltages ensure precision
• Includes watchdog timer for automated fault detection
• Manual reset input allows user-initiated system recovery

Supervisors Applications

• Microprocessor (μP) supervisory circuits
• Power supply monitoring in digital systems
• Watchdog timer applications
• Manual reset circuitry

Supervisors Procurement Notes

Verify the specific suffix BX against official Analog Devices documentation to confirm the exact reset threshold voltage and package variant. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production lot.

Supervisors Selection Notes

Select this component when a fixed 4.5V reset threshold is required for single-channel power monitoring. Ensure the application benefits from the integrated watchdog and manual reset features. Verify that the SOT-23-5 package dimensions fit the PCB layout constraints and that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are characterized by their miniature SOT-23 packaging and comprehensive feature sets including push/pull, open-drain, and bidirectional reset outputs. The family offers multiple factory-trimmed threshold options to cover various standard voltage rails.

Supervisors Replacement Considerations

Compatible substitutes include other members of the MAX6316–MAX6322 family with matching threshold voltages, such as MAX6320PUK46CY+T or MAX6320PUK46CX+T, provided the reset output type and timeout specifications align with the design requirements.
