Description and Introduction

+5V Microprocessor Supervisory Circuits The **MAX818LEPA** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:  

### **Manufacturer:** Maxim Integrated (Analog Devices)  
### **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Key Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (1.575V, 2.32V, 2.93V, 4.38V, etc.)  
- **Reset Timeout Period:** Adjustable (default 140ms min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  
- **Output Type:** Active-low RESET (open-drain or push-pull)  

### **Descriptions:**  
- Monitors system voltage and provides a reset signal to the microprocessor if the voltage drops below a preset threshold.  
- Ensures proper system initialization during power-up, power-down, or brownout conditions.  
- Available in fixed or adjustable threshold versions.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows external reset control via a pushbutton.  
- **Guaranteed Reset Valid Down to VCC = 1V**  
- **No External Components Required** (for fixed threshold versions)  
- **Hysteresis:** Prevents reset signal oscillation near the threshold.  

For exact threshold options and detailed electrical characteristics, refer to the official datasheet.
