Description and Introduction

+-1% accuracy, low-power, microprocessor supervisory circuit. Reset trip threshold (min) 4.50V (max) 4.60V, push-pull active-low reset output, push-pull active-high reset output, manual reset, power-fail monitor, low-line detector. The **MAX814NCPA** is a microprocessor (μP) supervisory circuit manufactured by **MAXIM**. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** MAXIM  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (4.38V, 4.63V, or 4.88V)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** 1.6s timeout (typical)  

### **Descriptions:**
- The **MAX814NCPA** monitors system power supply voltages and provides a reset signal to the microprocessor if the voltage drops below a preset threshold.  
- It includes a watchdog timer to detect software lockups and a manual reset input for external system resets.  
- Designed for reliability in microprocessor-based systems, ensuring proper initialization during power-up and brownout conditions.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Adjustable or Fixed Threshold:** Supports multiple reset voltage options.  
- **Watchdog Timer:** Detects system failures and triggers a reset.  
- **Manual Reset Input:** Allows for external reset control.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Guaranteed Reset Output Valid Down to VCC = 1V.**  

This information is strictly factual and based on the manufacturer's datasheet.
