Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809S is a microprocessor reset circuit manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Reset Timeout Period:** 140ms (min), 280ms (typ), 560ms (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 12µA (typ)  
- **Output Type:** Active-Low, Push-Pull  
- **Package Options:** SOT23-3  

### **Description:**  
The MAX809S is a low-power microprocessor reset monitor that asserts a reset signal when the supply voltage drops below a preset threshold. It ensures proper system operation by holding the reset signal active for a fixed timeout period after the supply voltage rises above the threshold.  

### **Features:**  
- Precision voltage monitoring for microprocessors  
- Guaranteed reset output down to VCC = 1V  
- No external components required  
- Low quiescent current (12µA typical)  
- Available in a small SOT23-3 package  
- Power-on reset pulse width of 280ms (typical)  

This information is based solely on the manufacturer's datasheet.
