ADM8698ARN-REEL

Supervisors Overview

The ADM8698ARN-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply input. It operates within a threshold voltage range of 3 V to 5.5 V and features a push-pull output type. The device provides a reset delay time of 280 ms and includes an over-voltage threshold detection capability at 4.75 V. It functions with a maximum power supply voltage of 5.5 V and consumes a working supply current of 100 uA. The component supports an operating temperature range from -40°C to +85°C and is housed in an 8-SOIC package.

Supervisors Feature Summary

• Monitors a single voltage input for under-voltage and over-voltage conditions
• Provides a dedicated reset signal via a push-pull output interface
• Includes internal timing for reset assertion delays
• Operates without manual reset or watchdog timer functionality

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation power management
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the exact threshold voltage variant required, as the series offers multiple options. Check RoHS compliance status details provided by the manufacturer. Ensure the source document explicitly lists this part number as available or discontinued before ordering.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with a push-pull output is required. Consider the 280 ms reset delay duration for system timing requirements. Evaluate the 100 uA supply current against low-power design constraints. Verify that the 8-SOIC package fits the PCB layout constraints compared to other package options in the series.

Supervisors Part Context

This part belongs to the ADM8698 series of improved voltage supervisors from Analog Devices. It serves as a successor to older models like the ADM698, offering enhanced performance characteristics. The series is categorized under PMIC - Power Management ICs, specifically within the Supervisory Circuits subcategory. It is designed for reliable operation in industrial and commercial environments.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+. These alternatives are listed as parameter equivalents by distributors. Verify pin compatibility and electrical specifications before substitution.
