ADM8693ARW

Supervisors Overview

The ADM8693ARW is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It features an active low push-pull output and includes a built-in watchdog timer with timeout reset functionality. The device operates within a supply voltage range of up to 5.5 V and maintains a threshold accuracy of 2.5%. It supports battery backup switching and offers a reset delay time of 35 ms minimum. The component is housed in a 16-SOIC package, suitable for surface mount installation, and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with timeout reset capability for system reliability.
• Provides battery backup switching functionality to maintain data integrity during power transitions.
• Features an active low push-pull output driver for direct interface with microprocessors.

Supervisors Applications

• Microprocessor system supervision
• Battery backup switching circuits
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix 'ARW' against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status as end-of-life or obsolescence may apply. Ensure compatibility with required operating temperature ranges and supply voltage thresholds before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog timing is required. Consider the 16-pin SOIC package size constraints and the need for battery backup switching. Verify that the 2.5% threshold accuracy meets the design requirements for the monitored voltage rail.

Supervisors Part Context

The ADM8693 belongs to the ADM869x family of improved supervisory circuits, serving as a successor to earlier ADM69x series devices. This family provides enhanced accuracy and additional features like watchdog timers compared to previous generations. The ARW variant specifically denotes the surface-mount package configuration within this product line.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM8693ANZ and ADM8693ARNZ. These variants offer equivalent electrical performance but differ in package style (DIP vs. SOIC) or manufacturing suffix. Verify pinout compatibility and thermal characteristics when substituting.
