Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX803SEXR+T** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated**.  

### **Specifications:**  
- **Type:** Voltage Monitor / Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Threshold Voltage Options:**  
  - 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:** 8μA (typ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-143-4  

### **Descriptions:**  
The **MAX803SEXR+T** monitors system voltage levels and provides a reset signal to the microprocessor when the voltage drops below a preset threshold. It ensures proper system operation by holding the reset signal until the voltage stabilizes.  

### **Features:**  
- Low power consumption  
- Precision voltage monitoring  
- Guaranteed reset output down to VCC = 1V  
- No external components required  
- Small SOT-143 package  
- Push-pull RESET output (active-low)  

This device is commonly used in **battery-powered systems, embedded controllers, and portable electronics** where reliable voltage monitoring is critical.
