ADM8698ARN

Supervisors Overview

The ADM8698ARN is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs. It features a push-pull output and operates within a threshold voltage range of 3 V to 5.5 V, with a specific threshold of 4.65 V. The device has a reset delay time of 140 ms minimum and consumes 100 uA of working power current. It supports a maximum power dissipation of 500 mW and functions in an operating temperature range from -40°C to +85°C. The component is housed in an 8-SOIC package.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality with a low-active signal.
• Features a push-pull/totem pole output configuration for robust drive capability.
• Monitors a single input channel for voltage supervision without manual reset requirements.

Supervisors Applications

• Voltage supervision in embedded systems
• Power management circuits requiring simple reset generation
• Microcontroller system protection

Supervisors Procurement Notes

Verify the obsolete status of the ADM8698ARN before procurement planning. Confirm availability through authorized distributors or alternative sources. Check for parameter-equivalent substitutes such as ADM709LARZ if original supply is unavailable. Ensure compliance with RoHS standards and verify package integrity upon receipt. Review datasheet specifications for any updates regarding environmental classifications or handling instructions.

Supervisors Selection Notes

Select this component for applications requiring a dedicated voltage supervisor with a fixed threshold near 4.65 V. Consider the 8-SOIC surface-mount package for PCB layout constraints. Evaluate the 140 ms reset delay against system timing requirements. Assess the 100 uA quiescent current impact on overall power budget. Verify compatibility with the target voltage range of 3 V to 5.5 V.

Supervisors Part Context

The ADM8698 belongs to the ADM8698/ADM8699 series of supervisory circuits from Analog Devices. It serves as an improved version of earlier models like the ADM698. The part is categorized under PMIC - Power Management ICs, specifically within the Supervisory Circuits subcategory. It is distinct from switching regulators like the LT8698 series.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+.
