Description and Introduction

3-pin microprocessor resets The MAX809ZD is a microprocessor reset circuit manufactured by Philips (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Reset Threshold Voltage Options:** Typically 4.63V (adjustable versions may exist).  
- **Operating Voltage Range:** 1.2V to 5.5V.  
- **Reset Timeout Period:** Typically 140ms (fixed).  
- **Output Type:** Active-low reset signal (open-drain or push-pull, depending on variant).  
- **Package Type:** SOT-23 (3-pin).  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade).  

### **Descriptions:**  
- The MAX809ZD is a voltage supervisor IC designed to monitor microprocessor power supplies.  
- It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring safe system operation.  
- It is commonly used in embedded systems, automotive electronics, and industrial applications.  

### **Features:**  
- **Low Power Consumption:** Typically draws 10µA (max).  
- **Guaranteed Reset Assertion:** Ensures reset signal remains active until voltage stabilizes.  
- **No External Components Required:** Simplifies circuit design.  
- **Small Form Factor:** SOT-23 package for space-constrained applications.  
- **Wide Operating Voltage Range:** Supports various power supply levels.  

For exact specifications, refer to the official datasheet from NXP (formerly Philips).
