MAX6320PUK29CY/V+T

Supervisors Overview

The MAX6320PUK29CY/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 2.9V with an overvoltage threshold of 2.974V. The device provides an active-low push-pull reset output with a standard 200ms timeout period. It integrates a watchdog timer and a manual reset input for enhanced system robustness. Operating on a single supply up to 5.5V, it draws only 10µA of quiescent current. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer and manual reset input for flexible design configurations
• Active-low push-pull reset output stage for direct logic interfacing
• Ultra-low 10µA operating current suitable for battery-powered applications
• Factory-trimmed reset threshold voltage ensuring precise supervision

Supervisors Applications

• Microprocessor (μP) power supply monitoring in digital systems
• Watchdog timer implementation for system stability
• Manual reset generation for user-initiated system recovery
• Battery-operated electronic devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix 'V' against the manufacturer's official datasheet to confirm if it denotes a valid commercial or industrial grade variant within the MAX6320 series. Confirm RoHS compliance status (+T indicates lead-free). Check current distribution availability as this part number may be subject to limited stock or factory special order constraints. Ensure the SOT-23-5 package matches your PCB footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.9V reset threshold is required for systems powered by lithium-ion or similar voltage rails. The integrated watchdog and manual reset features reduce external component count compared to discrete solutions. Consider the 200ms timeout period for compatibility with your microprocessor startup time. The SOT-23-5 package offers space savings for compact designs. Verify that the active-low push-pull output aligns with your target logic family requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are characterized by their integrated configuration options, including various reset thresholds, timeout periods, and output stages. The MAX6320 variant specifically utilizes the active-low push-pull output configuration. The family is designed to replace multiple discrete components, offering a compact solution for power management and system protection in embedded applications.

Supervisors Replacement Considerations

Direct substitutes within the same family include MAX6316LUK29CX+T and MAX6316LUK29CY+T, which share identical electrical characteristics and pinouts but may differ in packaging or manufacturing lot specifications. Cross-referencing the exact suffix codes is essential to ensure functional equivalence regarding temperature range and output type.
