Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809M is a microprocessor reset circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Voltage Monitoring Range:** 1.6V to 5.0V (adjustable via external resistors)  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 10µA (typical)  
- **Output Type:** Active-Low RESET (open-drain or push-pull options available)  
- **Temperature Range:** -40°C to +85°C (industrial grade)  
- **Package Options:** SOT23-3, SC70-3  

### **Descriptions:**  
The MAX809M is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems when the supply voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows external reset control (if applicable in variant).  
- **Small Form Factor:** Available in compact SOT23 and SC70 packages.  
- **No External Components Required:** Simplifies circuit design (for fixed threshold versions).  
- **Industrial Temperature Range:** Suitable for harsh environments.
