Description and Introduction

Microprocessor Supervisory Circuits The MAX805LCSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor Supervisor  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Multiple factory-set options (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5μA (typ)  

### **Descriptions:**  
The MAX805LCSA monitors system voltage levels and provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold. It ensures proper system operation by holding the μP in reset during power-up, power-down, and brownout conditions.  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current  
- **Precision Voltage Monitoring:** Accurate reset threshold options  
- **Manual Reset Input:** Allows external pushbutton reset control  
- **Power-On Reset (POR) Generation:** Ensures proper startup  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **No External Components Required:** Simplifies design  
- **Guaranteed Reset Valid Down to VCC = 1V**  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications requiring reliable power monitoring.
