MAX6865UK45D5S+T

Supervisors Overview

The MAX6865UK45D5S+T is a single-channel 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 4.5 V. The device provides an active high, push-pull output with manual reset capability and includes an integrated watchdog timer. It utilizes a SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault monitoring
• Provides manual reset functionality via dedicated input
• Delivers active high push-pull output signal

Supervisors Applications

• Single power supply supervision in embedded systems
• Microprocessor reset generation
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance documentation matches current regulatory requirements. Validate package marking and pinout alignment against official datasheets before integration into production designs.

Supervisors Selection Notes

Select this component when a 4.5 V threshold is required for single-supervision applications. Ensure the active high push-pull output aligns with downstream logic requirements. Verify that the SOT-23-5 footprint fits the PCB layout constraints and thermal management needs of the target application environment.
