- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Quiescent Current:** 12μA (typical)  

### **Descriptions:**  
The MAX814KCSA is a precision voltage monitor designed to ensure proper operation of microprocessors and digital systems. It monitors the power supply voltage and generates a reset signal if the voltage falls below a preset threshold. The device includes a manual reset input and a watchdog timer to enhance system reliability.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset generation during power-up, power-down, and brownout conditions.  
- **Manual Reset Input:** Allows for external system reset via a pushbutton.  
- **Watchdog Timer:** Monitors microprocessor activity; resets the system if the watchdog is not toggled within a set time.  
- **Low Power Consumption:** Typically draws 12μA, making it suitable for battery-powered applications.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset assertion even at very low voltages.  
- **Available in Multiple Threshold Voltages:** Supports various system voltage requirements.
