Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809J is a microprocessor reset circuit manufactured by Maxim Integrated (PHI).  

### **Specifications:**  
- **Reset Threshold Voltage:** 4.63V (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (minimum)  
- **Supply Current:** 12µA (typical)  
- **Output Type:** Active-low, open-drain  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 3-pin SOT23  

### **Descriptions:**  
The MAX809J is a low-power voltage monitor designed to provide a reset signal to microprocessors and 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  
- Low quiescent current  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required  
- Small 3-pin SOT23 package  

For exact details, refer to the official datasheet from Maxim Integrated.

Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809J is a microprocessor reset circuit manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor / Reset Circuit  
- **Reset Threshold Voltage:** 4.65V (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (minimum)  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 3-Pin SOT23  

### **Descriptions:**  
The MAX809J is a low-power microprocessor reset circuit that monitors system voltage and provides a reset signal to the processor when the voltage falls below a preset threshold. It ensures proper system initialization and prevents erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation at 4.65V threshold.  
- **Low Power Consumption:** Typically consumes 5µA supply current.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reset signal integrity even at low voltages.  
- **Push-Pull Output:** Eliminates the need for a pull-up resistor.  
- **Small Form Factor:** Available in a compact 3-pin SOT23 package.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
