MAX6865UK45D1S+T

Supervisors Overview

The MAX6865UK45D1S+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 reset threshold of 4.5 V. The device utilizes an SOT-23-5 surface-mount package and provides an active high, push-pull output. Key functional blocks include a manual reset input and a watchdog timer. The reset timeout period is specified at 15 ms. Operating temperatures range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring, manual reset, and watchdog timer functions in a compact five-pin package.
• Provides active high push-pull reset output for reliable logic interfacing.
• Features factory-trimmed fixed reset thresholds for precise power supervision.

Supervisors Applications

• Microprocessor (µP) power supply management
• Battery-powered portable equipment
• Consumer electronics requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the discontinued status. Confirm RoHS compliance and lead-free specifications against current inventory batches. Review datasheet revisions for any pinout or electrical characteristic updates prior to integration into new designs.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for single-supervision applications. Ensure the design accommodates the specific 15 ms reset timeout and active high output polarity. Verify that the SOT-23-5 footprint matches the PCB layout constraints and that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the MAX6865 series of ultra-low-current µP supervisory circuits. The family combines voltage monitoring with watchdog and manual reset capabilities. Variants differ primarily by reset threshold voltage and timeout duration while sharing the same core architecture and SOT-23-5 packaging.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked as discontinued, engineers should consult official cross-reference tools or contact Analog Devices directly for qualified replacement recommendations.
