Description and Introduction

3.3V/2.5V Multisupply Micromonitor The DS1831C is a microprocessor monitor manufactured by DALLAS (now part of Maxim Integrated). Below are its key specifications:

1. **Function**: Monitors power supply and microprocessor activity to prevent system lock-up.
2. **Voltage Monitoring**: Monitors VCC for out-of-tolerance conditions.
3. **Watchdog Timer**: Includes a watchdog timer to reset the system if the microprocessor fails to respond.
4. **Reset Output**: Provides an active-low reset signal (RST) when VCC falls below the threshold.
5. **Operating Voltage Range**: Typically 2.7V to 5.5V.
6. **Reset Threshold Accuracy**: ±2.5% (varies by model).
7. **Reset Timeout Period**: Adjustable or fixed (depending on variant).
8. **Temperature Range**: Commercial (0°C to +70°C) or industrial (-40°C to +85°C) options.
9. **Package**: Available in an 8-pin SOIC or DIP package.
10. **Applications**: Used in embedded systems, industrial controls, and computing devices.
