Description and Introduction

Very Low Supply Current 3-Pin Microprocessor Reset Monitors The MAX809SN232T1 is a microprocessor reset circuit manufactured by ON Semiconductor.  

### **Specifications:**  
- **Voltage Monitoring:** 2.32V threshold  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Voltage Range:** 1.1V to 5.5V  
- **Supply Current:** 6µA (typical)  
- **Output Type:** Active-low push-pull  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809SN232T1 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 (2.32V). It ensures proper system operation by holding the reset signal active until the voltage stabilizes.  

### **Features:**  
- Precision voltage monitoring  
- Low quiescent current  
- No external components required  
- Guaranteed reset output valid down to VCC = 1V  
- Push-pull RESET output (no external pull-up needed)  
- Small SOT-23-3 package  

This device is commonly used in embedded systems, automotive electronics, and industrial applications where reliable power monitoring is critical.
