Description and Introduction

Very Low Supply Current 3−Pin Microprocessor Reset Monitors The MAX809SQ308T1G is a microprocessor reset circuit manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Voltage Monitor  
- **Reset Threshold Voltage:** 3.08V (fixed)  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809SQ308T1G is designed to monitor microprocessor power supplies and provide a reset signal when the voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Typically 5µA supply current.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset assertion even at low voltages.  
- **Small Form Factor:** SOT-23-3 package for space-constrained applications.  

This device is commonly used in embedded systems, microcontrollers, and other digital circuits requiring reliable power monitoring.
