MAX6865UK21D6S+T

Supervisors Overview

The MAX6865UK21D6S+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors one input voltage with a threshold of 2.1 V and features an active high, push-pull output. The device includes manual reset capability and a watchdog timer. It operates within a supply voltage range up to 5.5 V and has a reset delay time of 900 ms. The component is housed in a SOT-23-5 package for surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Provides manual reset functionality via dedicated input
• Features active high push-pull output driver

Supervisors Applications

• Single power supply monitoring in embedded systems
• Watchdog timer implementation in microcontroller circuits
• Manual reset control in industrial equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices as this part may be discontinued. Ensure packaging specifications match project requirements before ordering.

Supervisors Selection Notes

Select this supervisor when a 2.1 V threshold is required for single-rail monitoring. Consider the 900 ms reset delay and watchdog integration if system stability requires these specific timing characteristics. Verify SOT-23-5 footprint compatibility during PCB layout.

Supervisors Part Context

This component belongs to the MAX6865 series of single nPower supervisors. The series offers various threshold voltages and reset delays to accommodate different power rail monitoring needs. The UK suffix indicates specific pinout and thermal characteristics within the Maxim portfolio.

Supervisors Replacement Considerations

Check MAX6865 variants with different threshold codes (e.g., D1, D4) for voltage compatibility. Verify equivalent parts from other manufacturers offering similar watchdog and manual reset features in SOT-23-5 packages.
