Description and Introduction

5V Adjustable, CMOS, Step-Down Switching Regulator The MAX638AEPA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (MAIXM)  
- **Type:** Microprocessor Voltage Monitor  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  
- **Manual Reset Input:** Yes (active-low)  
- **Output Type:** Active-low, open-drain  

### **Descriptions:**  
The MAX638AEPA+ is a low-power microprocessor supervisory circuit designed to monitor system voltage levels and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures reliable system operation by preventing erratic behavior due to unstable voltage.  

### **Features:**  
- **Low Power Consumption:** Only 5µA typical supply current.  
- **Precision Voltage Monitoring:** Accurate reset threshold (±1.5%).  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Manual Reset Capability:** Includes an active-low manual reset input.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Small Package:** Available in an 8-pin PDIP for easy integration.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

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