Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809REUR is a microprocessor reset circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor / Reset Circuit  
- **Reset Threshold Options:** Available in multiple fixed voltage options (e.g., 2.63V, 3.08V, 4.38V, etc., depending on variant)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** Typically 140ms (min)  
- **Output Type:** Active-Low, Push-Pull  
- **Package:** SOT23-3  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX809REUR is a low-power microprocessor reset circuit designed to monitor system voltage and assert a reset signal if the voltage drops below a preset threshold.  
- It ensures proper system operation by holding the reset signal active until the supply voltage stabilizes.  
- Suitable for battery-powered and embedded systems requiring reliable power-on reset functionality.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset assertion at the specified threshold.  
- **Low Quiescent Current:** Typically 5µA, making it suitable for power-sensitive applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliability even at low voltages.  
- **Compact SOT23-3 Package:** Space-efficient for small PCB designs.  

For exact threshold voltage options, refer to the specific part number suffix (e.g., MAX809LEUR for a different threshold).
