Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX818LCSA+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Series:** MAX818  
- **Package:** SOIC-8  
- **Type:** Voltage Monitor  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage:** Adjustable or Fixed (depends on variant)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some models)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** Typically 5μA  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX818LCSA+T monitors system voltage levels and provides a reset signal to the microprocessor when the voltage falls below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- Low quiescent current (5μA typical)  
- Precision voltage monitoring  
- Adjustable or fixed reset threshold options (depending on variant)  
- Guaranteed reset output valid down to VCC = 1V  
- Push-pull RESET output (no external pull-up resistor required)  
- Available in small SOIC-8 package  
- Industrial temperature range (-40°C to +85°C)  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable voltage monitoring is critical.
