MAX6865UK32D5S+T

Supervisors Overview

The MAX6865UK32D5S+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 3.2 V. The device utilizes an SOT-23-5 surface-mount package and draws a typical operating current of 7 µA. It provides an active high, push-pull reset output with a manual reset input and an integrated watchdog timer. The reset timeout period is specified at 450 ms, and the unit functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

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

Supervisors Applications

• Microprocessor system power management
• Battery-powered portable electronics
• Industrial control board supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain package integrity prior to assembly.

Supervisors Selection Notes

Select this component when a fixed 3.2 V supervision threshold is required for single-rail monitoring. The active high push-pull output suits applications needing strong drive capability. Verify that the 450 ms timeout aligns with system startup timing requirements and that the SOT-23-5 footprint fits the design layout constraints.

Supervisors Part Context

This part belongs to the MAX6865 series of ultra-low-current microprocessor supervisory circuits. The suffix 'UK' indicates a specific threshold voltage bin, while 'D5' denotes the SOT-23-5 package type. The '+T' suffix signifies tape-and-reel packaging for automated assembly processes within the Maxim Integrated product line.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Other variants within the MAX6865 family may offer different thresholds or output polarities but require electrical compatibility verification.
