Description and Introduction

Microprocessor Supervisory Circuits The ADM691AARNZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (ADI). It is designed to monitor the power supply voltage of microprocessor-based systems and provide reset signals during power-up, power-down, and brownout conditions. Key specifications include:

- **Supply Voltage Range**: 1.0V to 5.5V
- **Reset Threshold Accuracy**: ±1.5%
- **Reset Timeout Period**: 140ms (typical)
- **Operating Temperature Range**: -40°C to +85°C
- **Package**: 8-lead SOIC
- **Manual Reset Input**: Yes
- **Watchdog Timer**: Yes, with a timeout period of 1.6 seconds (typical)
- **Power-On Reset Delay**: 200ms (typical)
- **Low Quiescent Current**: 30µA (typical)

The ADM691AARNZ is commonly used in applications requiring reliable power supply monitoring and reset generation, such as embedded systems, industrial controls, and automotive electronics.

Description and Introduction

Microprocessor Supervisory Circuits The ADM691AARNZ is a microprocessor supervisory circuit manufactured by Analog Devices. It is designed to monitor the power supply voltage of microprocessor and digital systems. Key specifications include:

- **Supply Voltage Range**: 1.0V to 5.5V
- **Reset Threshold Accuracy**: ±1.5%
- **Reset Timeout Period**: 140ms (typical)
- **Operating Temperature Range**: -40°C to +85°C
- **Package**: 8-lead SOIC

The device provides a reset signal to the microprocessor when the supply voltage falls below a specified threshold, ensuring proper system initialization and operation. It also includes a watchdog timer and a manual reset input for additional system monitoring and control.
