Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX809LEUR+T** is a microprocessor reset circuit manufactured by **Maxim Integrated (now part of Analog Devices)**.  

### **Specifications:**  
- **Type:** Voltage Monitor / Reset IC  
- **Reset Threshold Voltage:** 2.93V (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
- Monitors system voltage and provides a reset signal to the microprocessor when voltage drops below a preset threshold.  
- Ensures proper system initialization during power-up, power-down, or brownout conditions.  
- Low quiescent current (typically 5µA) for power-sensitive applications.  

### **Features:**  
- **Precision Voltage Monitoring:** Accurate reset threshold (±2% tolerance).  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation.  
- **Push-Pull Output:** Eliminates the need for a pull-up resistor.  
- **Small Form Factor:** SOT-23-3 package for space-constrained applications.  

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