Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809TEXR+T is a microprocessor reset circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Type:** Voltage Monitor (Supervisor)  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage Options:** 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (selectable)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6µA (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809TEXR+T 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 reset functionality even at low voltages.  
- **Small SOT-23 Package:** Space-saving solution for compact designs.  

This device is commonly used in embedded systems, industrial controls, and portable electronics where reliable power-on reset functionality is critical.
