ADM8699ARN

Supervisors Overview

The ADM8699ARN is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and generate reset signals for microprocessor systems. It operates within a supply voltage range of 3 V to 5.5 V and features a push-pull output configuration. The device provides a fixed reset threshold voltage of 4.75 V with a typical reset delay time of 280 ms. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Monitors single power supply input for undervoltage conditions
• Generates active-low reset signal upon power-up or brown-out events
• Includes internal reset timeout timer to ensure stable initialization

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Industrial control board power management

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations may indicate different thermal grades or packaging formats. Confirm RoHS compliance status and lead-free certification requirements prior to integration. Check current lifecycle status, as this part number may be discontinued or subject to limited availability constraints.

Supervisors Selection Notes

Select this component when a fixed 4.75 V threshold is required for standard logic families. Ensure the 8-SOIC footprint matches the PCB layout constraints. Compare performance against the ADM8698 series if adjustable thresholds or manual reset inputs are needed instead of fixed operation.

Supervisors Part Context

This device belongs to the ADM869x family of supervisory circuits, which are engineered for reliable power management in embedded systems. It serves as a critical interface between power sources and digital logic, ensuring proper sequencing and protection against unstable voltage states during startup or fault conditions.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+. Verify pinout compatibility and electrical specifications before substitution.
