Description and Introduction

3-pin microprocessor resets The MAX809LW is a microprocessor reset circuit manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.2V to 5.5V  
- **Reset Threshold Options:** Available in multiple fixed voltages (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** Typically 140ms (fixed)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23 (3-pin)  
- **Low Quiescent Current:** Typically 10µA  

### **Descriptions:**  
- The MAX809LW is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems during power-up, power-down, or brownout conditions.  
- It ensures reliable system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset triggering at the specified threshold.  
- **Manual Reset Input:** Allows external reset control (if applicable in the variant).  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  

For exact threshold options and detailed electrical characteristics, refer to the official datasheet from NXP (formerly PHILIPS).
