ADM8693ARN

Supervisors Overview

The ADM8693ARN is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0V to 5.5V and features an adjustable reset threshold voltage, specifically noted at 4.4V in verified documentation. The device provides active-high or active-low reset signals with a minimum reset timeout of 35ms. It is housed in a 16-lead SOIC package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Adjustable reset threshold voltage allows customization for specific system requirements
• Push-pull output driver capability for robust signal integrity
• Supports both active-high and active-low reset signal configurations

Supervisors Applications

• Battery backup circuit monitoring
• Microprocessor power supply supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify component status as the ADM8693 family may be obsolete. Confirm package type matches design requirements. Check for RoHS compliance variations between suffixes. Validate supplier authenticity due to potential lifecycle changes. Review datasheet revisions for parameter updates before integration.

Supervisors Selection Notes

Select this component when adjustable threshold precision is required over fixed-voltage supervisors. Ensure the 16-lead SOIC package fits the PCB layout constraints. Verify that the 35ms minimum timeout meets system startup timing requirements. Consider thermal performance within the specified operating temperature range.

Supervisors Part Context

Part of the ADM869x series of supervisory circuits designed for reliable power management. The series includes variants with different packages and fixed thresholds. This specific model offers flexibility through its adjustable threshold feature, distinguishing it from fixed-threshold counterparts in the same product line.

Supervisors Replacement Considerations

ADM8693ARUZ (TSSOP package equivalent). Verify pin compatibility and package dimensions when substituting. Check if the alternative maintains the same adjustable threshold functionality and electrical characteristics.
