ADM8693ARWZ

Supervisors Overview

The ADM8693ARWZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and ensure system reliability. It features a single monitored input with a threshold voltage of 4.4 V and provides active high and active low push-pull outputs. The device includes an integrated watchdog timer with a minimum reset timeout of 35 ms and supports battery backup switching. Operating within a supply voltage range up to 5.5 V, it functions reliably across temperatures from -40°C to +85°C. Packaged in a 16-TSSOP surface-mount format, this component integrates power-fail detection capabilities for comprehensive voltage supervision.

Supervisors Feature Summary

• Integrated watchdog timer with programmable reset timeout functionality
• Dual output configuration providing both active high and active low signals
• Dedicated battery backup switch for seamless power source management
• Power-fail detection capability for monitoring supply integrity

Supervisors Applications

• Microprocessor system voltage supervision
• Battery-powered device power management
• Industrial control system reset circuits
• Embedded system power monitoring

Supervisors Procurement Notes

Verify current availability status as the component may be subject to limited supply or discontinuation notices. Confirm package compatibility and thermal requirements against design specifications. Check for updated documentation regarding pinout or electrical characteristics changes. Ensure compliance with RoHS directives and environmental regulations applicable to your region before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when dual-output supervision and watchdog functionality are required in a compact surface-mount package. Evaluate the 4.4 V threshold against target supply rails to ensure accurate triggering. Consider the 35 ms minimum timeout for system recovery timing. Verify that the 16-TSSOP footprint fits within board space constraints and thermal dissipation limits for the intended operating environment.

Supervisors Part Context

The ADM8693 belongs to the ADM869x family of supervisory circuits from Analog Devices, which includes variants like the ADM8690 and ADM8696. These devices share common features such as voltage monitoring and reset generation but differ in package types, thresholds, and specific functional integrations like chip enable signals or manual reset options. This model specifically targets applications requiring dual polarity outputs and watchdog integration.
