MAX6855UK40D6+T

Supervisors Overview

The MAX6855UK40D6+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 of up to 5.5 V and features a fixed threshold voltage of 4.0 V. The device provides an active high, push-pull output with a manual reset input capability. It includes a reset delay time of 900 ms and consumes only 7 uA of quiescent current. The component is housed in a compact SOT-23-5 package and supports operation across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 4.0 V threshold for reliable power system supervision.
• Features an active high, push-pull output driver suitable for direct interfacing with digital logic inputs.
• Includes a manual reset input pin allowing external control over the reset state generation.

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing efficient power management
• Microprocessor reset circuits in embedded applications

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your project requirements. Ensure proper handling procedures are followed during storage and installation to maintain device integrity.

Supervisors Selection Notes

Select this part when a fixed 4.0 V threshold is required for single-supply monitoring. Consider the active high output polarity and manual reset feature for system design compatibility. Evaluate the 7 uA quiescent current against battery life requirements. Compare package size and thermal characteristics with alternative supervisors if space is limited.

Supervisors Part Context

This component belongs to the MAX6855 series of single nPower Supervisors designed for low-voltage applications. The series offers various threshold options to accommodate different rail voltages. The UK suffix indicates a specific package variant within the broader product family, ensuring compatibility with standard surface-mount assembly processes.

Supervisors Replacement Considerations

Check for MAX6855 variants with similar thresholds and output types. Verify pinout compatibility before substitution. Consider MAX6854 or MAX6865 series parts if different output polarities or additional features like watchdog timers are acceptable for the application.
