MAX6321HPUK46CY-T

Supervisors Overview

The MAX6321HPUK46CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.7V to 5.5V and features a fixed reset threshold voltage of 4.6V. The device provides an active-low, open-drain reset output with a typical delay time of 200ms. It includes manual reset functionality and a watchdog timer for system monitoring. The component is housed in a compact SOT-23-5 surface-mount package and supports industrial operating temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Provides an active-low open-drain reset output compatible with various logic families
• Operates over an extended industrial temperature range of -40°C to +125°C

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for digital control circuits
• Manual reset generation for system recovery

Supervisors Procurement Notes

Verify the exact suffix 'T' against official datasheets, as standard listings often use '+T'. Confirm availability status directly with Analog Devices or authorized distributors, as this specific variant may be subject to limited supply or discontinuation. Ensure the package type matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supply monitoring. The combination of watchdog and manual reset features makes it suitable for applications requiring both automated fault detection and user-initiated recovery. Verify that the open-drain output configuration aligns with the pull-up resistor requirements of your target logic interface.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and processor activity in digital systems. The family offers various combinations of reset outputs and features, including watchdog timers and manual resets, available in multiple threshold voltages.

Supervisors Replacement Considerations

Consider the MAX6321HPUK46CY+T as a direct equivalent if the 'T' suffix denotes tape-and-reel packaging. Other family members like MAX6316 or MAX6320 offer similar functions but may differ in output type or threshold voltage.
