MAX6320PUK31BX

Supervisors Overview

The MAX6320PUK31BX is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 3.1 V. The device provides an active low, open-drain output with a manual reset input capability. It incorporates a watchdog timer function and offers a reset delay time of 200 ms. The component is housed in a 5-pin SOT-23 package and supports surface mount installation. It functions as a single-channel power supply management circuit designed for reliable system monitoring.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery
• Includes a manual reset input for user-initiated control
• Provides active low open-drain output signaling

Supervisors Applications

• Portable equipment requiring low standby current
• Battery-powered systems needing voltage supervision
• Microcontroller-based embedded designs

Supervisors Procurement Notes

Verify the specific suffix 'BX' against official Analog Devices documentation to confirm exact temperature grade and tape-and-reel specifications. Ensure compatibility with RoHS directives if required for your region. Confirm that the SOT-23-5 footprint matches your PCB layout constraints. Cross-reference the manufacturer part number directly on the Analog Devices website to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold is required for system monitoring. Consider the integrated watchdog feature if software reliability is critical. The low operating current makes it suitable for battery-operated devices. Verify that the 200 ms reset delay meets your system startup timing requirements. Ensure the open-drain output configuration aligns with your microcontroller input logic levels.

Supervisors Part Context

This part belongs to the MAX6320 family of voltage supervisors from Maxim Integrated, now part of Analog Devices. These circuits are designed to monitor power supply voltages and generate reset signals for digital systems. The family typically includes variants with different thresholds and additional features like watchdog timers.
