Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX809SEUR+T** is a microprocessor reset circuit manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** MAXIM (Analog Devices)  
- **Type:** Voltage Monitor / Reset IC  
- **Reset Threshold Voltage:** Adjustable or fixed (depending on variant)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** Typically 140ms (adjustable in some models)  
- **Output Type:** Active-Low, Push-Pull  
- **Package:** SOT-143 (4-Pin)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The **MAX809SEUR+T** is a low-power microprocessor reset circuit designed to monitor system voltage levels and provide a reset signal if the voltage drops below a specified threshold.  
- It ensures proper system initialization by holding the microprocessor in reset until the supply voltage stabilizes.  
- Available in multiple threshold voltage options to suit different applications.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Quiescent Current:** Typically 5µA, making it suitable for battery-powered applications.  
- **Manual Reset Input:** Allows external reset triggering.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures operation even at low voltages.  
- **Small Form Factor:** SOT-143 package for space-constrained designs.  

This IC is commonly used in embedded systems, industrial controls, and consumer electronics where reliable power-on reset functionality is required.  

(Note: Always refer to the latest datasheet for exact specifications.)
