MAX6865UK25D5S+T

Supervisors Overview

The MAX6865UK25D5S+T is a single-channel 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 threshold voltage of 2.625 V. The device utilizes an SOT-23-5 surface-mount package and draws a typical operating current of 7 uA. Key functional parameters include an active high push-pull output, a manual reset capability, and an integrated watchdog timer. The reset delay time is specified at 450 ms, with an overvoltage threshold of 2.691 V. It supports an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault monitoring alongside voltage supervision.
• Provides manual reset functionality in addition to automatic power-on reset.
• Features an active high push-pull output stage for direct logic interfacing.

Supervisors Applications

• Embedded systems requiring reliable power management
• Microcontroller-based designs needing watchdog protection
• Portable electronics with low-power constraints

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and manufacturing origin via official documentation. Check for obsolescence notices or lifecycle changes from Analog Devices. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Supervisors Selection Notes

Select this part when a single-supply supervisor with watchdog integration is required. Consider the 2.625 V threshold for specific rail monitoring needs. Evaluate the 450 ms reset delay against system startup timing requirements. Compare against other MAX686x variants if different thresholds or output polarities are needed.

Supervisors Part Context

This component belongs to the MAX6865 series of single nPower Supervisors. It shares common architectural features with siblings like the MAX6864 and MAX6869 but differs in threshold voltage and output configuration. The series is designed for compact applications using the SOT-23-5 footprint.
