MAX6821YUK-T

Supervisors Overview

The MAX6821YUK-T is a low-voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.19 V with an accuracy of 2.5%. The device provides a manual reset input, a watchdog timer, and an active low push-pull output. It includes a reset delay time of 200 ms and consumes only 10 uA of quiescent current. Designed for surface mount installation in a SOT-23-5 package, it functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a manual reset button interface for user-initiated system recovery.
• Includes a built-in watchdog timer to detect software malfunctions.
• Provides an active low push-pull output driver for direct logic interfacing.

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing reliable voltage monitoring
• Embedded controllers utilizing manual reset capabilities

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 2.19 V threshold is required for single-channel monitoring. Consider the 10 uA quiescent current for battery-sensitive designs. The inclusion of both manual reset and watchdog functionality makes it suitable for complex embedded applications. Verify that the SOT-23-5 package size fits within the available board space constraints.

Supervisors Part Context

This part belongs to the MAX6823 series family of low-voltage supervisors. It shares functional similarities with other members like the MAX6823YUK+T but differs in specific threshold voltages and feature sets. The series is designed for general-purpose voltage monitoring in portable and industrial electronics where space and power consumption are critical factors.

Supervisors Replacement Considerations

The MAX6823YUK+T is a related part within the same series. Verify threshold voltage compatibility (2.19 V) and package type (SOT-23-5) before substitution. Ensure the replacement supports the required manual reset and watchdog features if these are critical to the design.
