MAX6865UK20D2S+T

Supervisors Overview

The MAX6865UK20D2S+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 2 V. The device provides an active high, push-pull output with a manual reset input and an integrated watchdog timer. It consumes 7 µA of operating current and offers a reset delay time of 15 ms. The component is housed in a SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring, manual reset, and watchdog timer functions in a compact five-pin surface-mount package.
• Provides an active high, push-pull reset output for direct interface with digital logic systems.
• Features factory-trimmed fixed reset threshold voltages to ensure accurate supervision without external components.

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery-powered equipment voltage supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm that the specific suffix D2S corresponds to the 2 V threshold variant in official documentation. Check for RoHS compliance details as indicated in manufacturer records. Ensure alternative sources are identified due to discontinuation. Validate pinout compatibility if substituting with similar family members.

Supervisors Selection Notes

Select this part when a low-current, single-supervisor solution with manual reset capability is required. The active high output suits applications needing positive logic reset signals. Consider the 15 ms timeout period against system startup requirements. Evaluate the SOT-23-5 footprint constraints against available board space. Verify that the 2 V threshold aligns with the monitored rail's minimum operating voltage.

Supervisors Part Context

This component belongs to the MAX6865 series of nanopower microprocessor supervisory circuits. The series combines voltage monitoring, watchdog, and manual reset functions. Other variants in the family offer different threshold voltages and timeout periods while maintaining the same package and core functionality.
