Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX819LCPA is a microprocessor (µP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX819LCPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5µA (typical)  

### **Descriptions:**  
The MAX819LCPA is a low-power µP supervisory circuit designed to monitor system voltage levels and provide a reset signal to the microprocessor in case of power failure or brownout conditions. It ensures reliable system operation by holding the µP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Low-Power Operation:** Consumes minimal current (5µA typical).  
- **Precision Voltage Monitoring:** Ensures accurate reset triggering.  
- **Adjustable or Fixed Threshold:** Supports factory-set or user-defined reset thresholds.  
- **Power-Fail Comparator:** Provides early warning for impending power loss.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable reset assertion even at low voltages.  

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