MAX6865UK43D5S+T

Supervisors Overview

The MAX6865UK43D5S+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 up to 5.5 V and features an active high, push-pull output. The device includes a manual reset input and an integrated watchdog timer. It provides a threshold voltage of 4.3 V with a reset delay time of 450 ms. The component is designed for surface mount installation in a SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

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

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to discontinued status. Confirm RoHS compliance and lead times with suppliers. Check for alternative sources as availability may be limited. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Supervisors Selection Notes

Select this part when a single-supervisor with watchdog and manual reset is required. Compare threshold voltages against other MAX6865 variants if different trip points are needed. Verify package compatibility with existing PCB footprints. Consider operating temperature range for environmental suitability.

Supervisors Part Context

This component belongs to the MAX6865 series of single nPower supervisors. It shares functional similarities with other parts in the family but differs in specific threshold voltages and reset delays. The series is designed for compact power management applications requiring reliable supervision in small form factors.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6865 series with adjusted threshold voltages. Verify electrical parameters match application requirements before substitution.
