Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX809JEUR+T** is a microprocessor (μP) supervisory 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 / Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Threshold Voltage:** 2.93V (J-grade)  
- **Accuracy:** ±1.5%  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**
The MAX809JEUR+T is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal to μPs or microcontrollers when the voltage falls below a preset threshold. It ensures proper system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Only 6μA typical supply current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset assertion even at very low voltages.  
- **No External Components Required:** Simplifies circuit design.  
- **Small SOT-23-3 Package:** Space-saving solution for compact designs.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.
