Microprocessor Supervisory Circuits The ADM691SQ is a microprocessor supervisory circuit manufactured by Analog Devices. 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% (typical)
- **Reset Timeout Period**: 200ms (typical)
- **Operating Temperature Range**: -40°C to +85°C
- **Package**: 8-pin SOIC (Small Outline Integrated Circuit)
- **Manual Reset Input**: Yes
- **Watchdog Timer**: Yes, with a programmable timeout period
- **Power-On Reset Delay**: Adjustable via external capacitor
- **Low Quiescent Current**: Typically 20µA
