ADM8693ARU

Supervisors Overview

The ADM8693ARU is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input with a threshold of 4.4V and features active high/low push-pull outputs. The device includes a watchdog timer, battery backup switch, and power-fail detection. It operates within a supply voltage range up to 5.5V and maintains an accuracy of 2.5%. The reset delay time is 35ms minimum. Operating temperatures span from -40°C to +85°C, and the part is housed in a 16-TSSOP package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch functionality for seamless power transitions
• Power-fail detection capability for voltage anomaly alerts
• Push-pull output configuration supporting active high or low signals

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Industrial control systems requiring voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against the 16-TSSOP specification. Ensure thermal handling meets the specified operating temperature range during installation. Cross-reference datasheet revisions for any parameter updates prior to integration into final designs.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and battery backup is required. The 4.4V threshold suits standard 5V logic systems. Consider the 16-TSSOP package for surface-mount applications needing higher pin counts than SOIC-8 variants offer. Verify that the 35ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

The ADM8693ARU belongs to the ADM869x family of supervisory circuits from Analog Devices. This series provides enhanced features over earlier generations, including improved accuracy and additional monitoring functions like watchdog timers. The ARU suffix indicates the specific 16-TSSOP surface-mount package variant within the broader product line.
