ADM8699ARNZ-REEL

Supervisors Overview

The ADM8699ARNZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features an adjustable reset threshold voltage. The device provides active-low and active-high push-pull outputs with a typical reset delay time of 140 ms. It includes a manual reset input, a watchdog timer, and battery backup switching capabilities. The component is housed in an 8-SOIC package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Supports battery backup switching functionality
• Provides both active-low and active-high output signals

Supervisors Applications

• Microprocessor power supply monitoring
• Watchdog timer implementation in embedded systems
• Battery backup switching circuits

Supervisors Procurement Notes

Verify the specific suffix 'ARNZ-REEL' against official Analog Devices documentation to confirm the reel packaging configuration and RoHS compliance status. Ensure the order matches the required SOIC-8 surface-mount package and that the adjustable threshold requirements align with the component's specifications before procurement.

Supervisors Selection Notes

Select this component when an adjustable reset threshold is required alongside integrated watchdog and battery backup functions. Compare performance against fixed-threshold alternatives like the ADM709 series if programmability is not needed. Verify that the 140 ms reset delay meets the timing constraints of the target application logic.

Supervisors Part Context

This part belongs to the ADM869x family of supervisory circuits from Analog Devices. These devices are designed to monitor voltage levels and provide reliable reset signals for digital systems. The family typically includes variants with different packages and fixed or adjustable thresholds, serving as critical components for system stability.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADM709LARZ and the ADM8698ARN. Cross-reference datasheets to ensure compatibility regarding reset delay times, output configurations, and operating voltage ranges before substitution.
