MAX6865UK22D3L+T

Supervisors Overview

The MAX6865UK22D3L+T is a single-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold of 2.188 V with an overvoltage threshold of 2.243 V. The device provides an active low, push-pull output and includes a manual reset input alongside a watchdog timer function. It ensures system reliability with a minimum reset timeout of 900 ms and functions across a temperature range of -40°C to +85°C in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for automated fault recovery
• Includes a manual reset input for user-controlled system resets
• Provides active low push-pull output signaling
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Portable equipment requiring reliable power monitoring
• Battery-powered systems needing supervisory control
• Microprocessor reset circuits in embedded designs
• Consumer electronics with strict power management needs

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance and lead-free soldering specifications. Check for obsolescence notices from Analog Devices. Ensure storage conditions meet moisture sensitivity level requirements. Validate part number suffixes against official datasheets to confirm pinout and electrical characteristics match design specifications.

Supervisors Selection Notes

Select this component when a single-supply supervisor with integrated watchdog functionality is required. The fixed 2.188 V threshold suits applications monitoring 3.3 V or similar logic levels. The manual reset feature allows external intervention during debugging. Consider the SOT-23-5 package for space-constrained PCB layouts. Verify that the 900 ms timeout aligns with system startup requirements.

Supervisors Part Context

This part belongs to the MAX6865 series of single nPower supervisors designed for portable applications. It complements other Maxim Integrated monitoring solutions by offering combined voltage supervision and watchdog timing in a minimal footprint. The series supports various threshold voltages to accommodate different logic families and battery chemistries commonly used in consumer and industrial electronics.

Supervisors Replacement Considerations

MAX6865UK22D3L+T is listed as discontinued. No direct public substitute part numbers are confirmed in the provided documentation. Engineers should consult Analog Devices for current equivalent recommendations or evaluate alternative single-channel supervisors with matching threshold and package specifications.
