MAX6865UK28D2L+T

Supervisors Overview

The MAX6865UK28D2L+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 monitors a specific threshold voltage of 2.8 V with an overvoltage threshold of 2.87 V. It includes a manual reset input and a watchdog timer function. The reset delay time is specified at 900 ms. Operating current is 7 uA, and it supports an extended temperature range from -40 C to +85 C. The component is housed in a SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset capability via dedicated input pin
• Features active high push-pull output driver
• Operates with low quiescent current consumption

Supervisors Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery-powered circuit protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and lead times prior to integration into production schedules. Ensure packaging specifications match assembly requirements. Cross-reference datasheet revisions for any parameter updates.

Supervisors Selection Notes

Select this component when a fixed 2.8 V threshold is required for single-supply monitoring. The active high output suits logic families requiring positive assertion. Verify that the 900 ms reset delay aligns with system startup timing requirements. Consider the SOT-23-5 footprint constraints during PCB layout design.

Supervisors Part Context

This part belongs to the MAX6865 series of single nPower supervisors. It shares functional similarities with other variants in the family but differs in threshold voltage settings. The UK suffix indicates the specific package type and thermal characteristics. It is designed for applications requiring compact supervision solutions with integrated watchdog functionality.

Supervisors Replacement Considerations

Direct substitutes include MAX6865UK28D3L+T and MAX6865UK28D6S+T, which share identical package and functional profiles but may differ in threshold tolerances or reset delays. Verify electrical parameters against original design specifications before substitution.
