Description and Introduction

3-pin microprocessor resets The MAX809LD is a microprocessor reset circuit manufactured by Philips (now NXP Semiconductors).  

### **Specifications:**  
- **Type:** Voltage Monitor / Reset IC  
- **Reset Threshold Voltage:** Typically 4.65V (adjustable variants may exist)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Output Type:** Active-Low Reset  
- **Reset Timeout Period:** Typically 140ms (fixed delay)  
- **Package:** SOT-23 (3-pin)  
- **Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- Monitors system voltage and provides a reset signal to the microprocessor if the voltage drops below a preset threshold.  
- Ensures proper system initialization and prevents erratic operation during power-up/down.  

### **Features:**  
- Low power consumption.  
- No external components required for basic operation.  
- Guaranteed reset valid down to Vcc = 1V.  
- Immune to short voltage transients.  
- Available in various threshold voltages (e.g., 2.93V, 3.08V, 4.38V, 4.63V).  

(Note: Exact specifications may vary; always refer to the official datasheet for precise details.)
