Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX809LEXR+** is a microprocessor reset circuit manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** MAXIM (Analog Devices)  
- **Type:** Voltage Monitor / Reset Circuit  
- **Reset Threshold Voltage:** 2.93V (adjustable variants available)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Output Type:** Active-Low, Push-Pull  
- **Package:** SOT-143 (4-pin)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6µA (typ)  

### **Descriptions:**  
- The MAX809LEXR+ is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems when the supply voltage drops below a preset threshold.  
- It ensures proper system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures functionality even at low voltages.  
- **Small Form Factor:** Available in a compact SOT-143 package.  

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