MAX6865UK26D3S+T

Supervisors Overview

The MAX6865UK26D3S+T is a single-channel voltage supervisor integrated 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 precise reset threshold of 2.625 V. The device provides an active-low, push-pull/totem-pole output signal with a minimum reset timeout of 150 ms. Designed for surface-mount installation in SOT-23-5 packages, it supports an operating temperature range from -40°C to +85°C. This component ensures reliable system monitoring and controlled power-up sequencing.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage rails
• Features an active-low output with push-pull or totem-pole drive capability
• Includes manual reset input for external control of the reset state

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Portable electronic devices

Supervisors Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification should confirm availability through authorized distributors or surplus channels. Ensure that any sourced units match the original specifications and packaging requirements. Cross-reference part numbers carefully to avoid counterfeit components. Check for alternative replacement parts if new production is required.

Supervisors Selection Notes

Select this part when a fixed 2.625 V threshold is required for single-rail monitoring. Verify compatibility with the target logic levels due to the active-low output configuration. Consider the 150 ms minimum timeout duration against system startup requirements. Confirm that the SOT-23-5 package fits the PCB layout constraints. Evaluate thermal performance within the specified operating temperature range.

Supervisors Part Context

The MAX6865 series comprises nanopower voltage supervisors designed for low-power applications. These devices monitor a single voltage supply and generate a reset signal when the supply drops below a specific threshold. The UK suffix indicates a specific threshold voltage variant, while D3S denotes the package type and tape/reel packaging. This family emphasizes simplicity and reliability for basic power management tasks.
