MAX6855UK21D3+T

Supervisors Overview

The MAX6855UK21D3+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 a threshold voltage of 2.1 V with an overvoltage threshold of approximately 2.16 V. The device provides an active high, push-pull output and includes manual reset functionality. It has a minimum reset delay time of 150 ms and consumes 7 uA of operating current. The component is housed in a SOT-23-5 package (SC-74A/SOT-753) and supports surface mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset monitoring for a single input channel
• Features active high push-pull/totem pole output configuration
• Includes manual reset capability for system control
• Operates with low quiescent current consumption

Supervisors Applications

• Portable equipment requiring voltage supervision
• Battery-powered systems needing power management
• Consumer electronics with microprocessor reset requirements
• Industrial control systems utilizing single-supply logic

Supervisors Procurement Notes

Verify part status as obsolete before procurement planning. Confirm RoHS compliance and REACH status through official manufacturer documentation. Check for tariff implications if shipping to specific regions. Ensure compatibility with existing PCB footprint and design specifications given the discontinued status.

Supervisors Selection Notes

Select this component for applications requiring a 2.1 V threshold with active high output. Consider the 150 ms reset timeout and manual reset feature when designing system recovery logic. Verify that the SOT-23-5 package fits the mechanical constraints. Evaluate alternative components from the same family if availability is critical due to obsolescence.

Supervisors Part Context

This part belongs to the MAX6855 series of single-supervisory circuits. It shares the SOT-23-5 package and basic architecture with other variants like MAX6855UK37D2+T but differs in threshold voltage and output polarity. The series is designed for low-power, space-constrained applications requiring reliable voltage monitoring without watchdog timer complexity.
