MAX6865UK31D3S+T

Supervisors Overview

The MAX6865UK31D3S+T is a single-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an ambient temperature range of -40°C to +85°C and utilizes a SOT-23-5 surface-mount package. The device features a fixed reset threshold voltage of 3.075V with a minimum reset timeout period of 150ms. It provides a low-active push-pull/totem pole output for simple reset or power-on reset functions. The component is RoHS compliant, classified as EAR99, and has reached end-of-life status.

Supervisors Feature Summary

• Provides automated system reset via low-active push-pull output when monitored voltage drops below the specified threshold.
• Ensures reliable microcontroller initialization through a guaranteed minimum reset timeout duration during power-up sequences.
• Supports manual intervention capabilities allowing external triggering of the reset state via dedicated input connections.

Supervisors Applications

• Embedded systems requiring precise power supply monitoring for stable operation
• Microcontroller-based designs needing reliable power-on reset generation
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer allocation. Confirm exact lot dates and storage conditions due to potential shelf-life limitations associated with obsolete inventory. Ensure compatibility with existing PCB footprints before sourcing replacement quantities from alternative suppliers.

Supervisors Selection Notes

Engineers replacing this part must verify that the substitute component matches the 3.075V threshold and 150ms timeout specifications. The SOT-23-5 package dimensions must align with existing board layouts. Consider whether the low-active output polarity meets the target system logic requirements. Evaluate if the industrial temperature range suffices for the intended operational environment without derating concerns.

Supervisors Part Context

Part of the MAX6865 series supervisory circuits designed for single-input voltage monitoring. This specific suffix denotes the 3.075V threshold variant housed in a compact five-pin surface-mount package. The series supports basic reset functionalities for embedded applications where cost-effective power management is prioritized over complex sequencing features.

Supervisors Replacement Considerations

Public confirmed substitutes include MAX6865UK31D3L+T and MAX6865UK31D5L+T. These variants share identical electrical characteristics but differ in packaging style. Verify pinout compatibility and thermal performance when transitioning between these specific package options.
