ADM9690ARNZ

Supervisors Overview

The ADM9690ARNZ is a supervisory circuit manufactured by Analog Devices Inc., housed in an 8-lead SOIC package. It features a threshold voltage of 4.31 V and supports a maximum supply voltage of 5.5 V. The device provides push-pull, active-low reset outputs with typical timeout durations of 10 ms and 50 ms. It operates within an industrial temperature range of -40°C to +85°C, consumes 0.1 mA of supply current, and has a power dissipation rating of 400 mW.

Supervisors Feature Summary

• Provides dual reset output options with selectable timeout delays for flexible system protection
• Features push-pull output stage for robust drive capability without external pull-up resistors
• Includes internal battery backup switch functionality for seamless power transition monitoring

Supervisors Applications

• Portable equipment requiring low standby current consumption
• Battery-powered systems needing reliable power-fail detection
• Industrial control units operating in wide temperature environments

Supervisors Procurement Notes

Verify the specific revision and packaging configuration against the official datasheet before procurement. Confirm that the 8-lead SOIC package meets your PCB footprint requirements. Ensure the selected component matches the required reset timeout specifications for your application timing constraints. Check for any end-of-life notices or obsolescence warnings from the manufacturer prior to finalizing orders.

Supervisors Selection Notes

Select this component when a push-pull output is preferred over open-collector types to simplify circuit design. Consider the 4.31 V threshold if it aligns with your system's nominal voltage levels. Evaluate the 10 ms and 50 ms reset delay options against your microcontroller startup requirements. Verify that the 400 mW power dissipation rating is sufficient for your thermal management strategy.

Supervisors Part Context

This part belongs to the ADM9690 series of supervisory circuits designed for monitoring power supplies in portable and industrial applications. It integrates essential functions such as power-fail detection and manual reset capabilities into a compact surface-mount package. The series is engineered to provide reliable system supervision with minimal external component count.

Supervisors Replacement Considerations

Check for ADM9690 variants with different reset timeouts or output configurations. Verify pin compatibility with existing designs if substituting with other supervisory ICs. Ensure replacement parts meet the same industrial temperature range and voltage threshold specifications.
