ADM8691ARUZ

Supervisors Overview

The ADM8691ARUZ is a voltage supervisory circuit manufactured by Analog Devices Inc., housed in a 16-pin TSSOP package. It features a maximum supply voltage of 5.5 V and monitors a single input with a threshold of 4.65 V. The device includes an open-drain or push-pull output, a watchdog timer, and a reset delay time of 280 ms. Operating within a temperature range of -40°C to +85°C, it draws 100 µA of supply current and supports power-fail detection.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Configurable output driver supporting both open-drain and push-pull configurations
• Built-in power-fail detection capability
• Includes backup battery switch functionality

Supervisors Applications

• Voltage supervision in embedded systems
• Watchdog timer implementation in microcontroller circuits
• Power-fail detection in portable devices

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Cross-reference pinout and electrical specifications with the manufacturer's documentation before integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and configurable output is required. Ensure the monitored voltage aligns with the 4.65 V threshold. Verify that the operating temperature range meets environmental constraints and that the 5.5 V maximum supply voltage suits the system power rail.

Supervisors Part Context

This part belongs to the ADM8691 family of voltage supervisors from Analog Devices. It is designed for low-power applications requiring reliable reset generation and system monitoring. The TSSOP-16 package allows for compact surface-mount integration in space-constrained designs.
