ADM8324WCA29ARJZR7

Supervisors Overview

The ADM8324WCA29ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails in automotive applications. It features an open-drain or open-collector output that asserts a low-active reset signal when the monitored voltage falls below the 2.93V threshold. The device integrates a windowed watchdog timer and a manual reset input, providing comprehensive system protection. It operates within a temperature range of -40°C to 125°C and is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer with manual reset capability for robust system supervision
• Provides low-active reset output via open-drain or open-collector configuration
• Engineered specifically for automotive-grade reliability and high-temperature operation

Supervisors Applications

• Automotive power supply monitoring systems
• Microcontroller reset supervision in vehicle electronics
