Description and Introduction

Supervisory circuit with +-1.5% reset accuracy. Reset threshold(typ) 4.425V. CMOS RAM write protection.. The MAX808MEPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor 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 (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable with external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 5μA (low power consumption)  

### **Descriptions:**
- The MAX808MEPA monitors system voltage and provides a reset signal to the microprocessor if the voltage falls below a preset threshold.  
- It ensures proper system operation by holding the μP in reset during power-up, power-down, or brownout conditions.  
- Suitable for battery-powered and low-voltage applications due to its wide operating range.  

### **Features:**
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR) Circuitry:** Guarantees a valid reset signal at power-up.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Adjustable Reset Threshold:** Can be configured for different voltage levels.  
- **Wide Operating Voltage Range:** Supports systems from 1.2V to 5.5V.  
- **No External Components Required:** Fixed threshold versions simplify design.  

This device is commonly used in embedded systems, industrial controls, and portable electronics for reliable power monitoring.  

(Note: Always refer to the official datasheet for detailed electrical characteristics and application guidelines.)
