Description and Introduction

Very Low Supply Current 3−Pin Microprocessor Reset Monitors The MAX809SQ293T1G is a microprocessor reset circuit manufactured by ON Semiconductor. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Type:** Voltage Monitor  
- **Reset Threshold Voltage:** 2.93V  
- **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 MAX809SQ293T1G is a low-power voltage monitor designed to ensure proper system operation by resetting microprocessors during power-up, power-down, or brownout conditions.  
- It asserts a reset signal when the supply voltage drops below the preset threshold (2.93V).  

### **Features:**  
- **Precision Monitoring:** Accurate 2.93V threshold with ±2% tolerance.  
- **Low Quiescent Current:** Typically 5µA, reducing power consumption.  
- **No External Components Required:** Simplifies circuit design.  
- **Push-Pull Output:** Eliminates the need for an external pull-up resistor.  
- **Wide Voltage Range:** Operates from 1.2V to 5.5V.  
- **Small Form Factor:** Available in a compact SOT-23-3 package.  

This information is based solely on the manufacturer's datasheet.

- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809SQ293T1G is a low-power voltage monitor designed to provide a reset signal to microprocessors and other digital systems when the supply voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, and brownout conditions.  

### **Features:**  
- Precision voltage monitoring  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required  
- Small SOT-23-3 package  
- ESD protection (Human Body Model: 2000V)  

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