Description and Introduction

Supervisory circuit with +-1.5% reset accuracy. Reset threshold(typ) 4.675V. CMOS RAM write protection.. The MAX808LCSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX808LCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Type:** Microprocessor Voltage Monitor/Supervisor  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (min)  
- **Quiescent Current:** 5μA (typical)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Output Type:** Active-low, push-pull RESET  

### **Descriptions:**  
The MAX808LCSA monitors system voltage levels and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- Low quiescent current (5μA) for power efficiency  
- Precision voltage monitoring with factory-set or adjustable thresholds  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required for fixed threshold versions  
- Push-pull RESET output (active-low)  
- Immune to short VCC transients  
- Small 8-pin SOIC package for space-constrained applications  

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

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX808LCSA  
- **Package:** 8-Pin SOIC  
- **Type:** Voltage Monitor/Supervisory IC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-Set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**  
The MAX808LCSA is a low-power microprocessor voltage monitor designed to ensure proper system operation during power-up, power-down, and brownout conditions. It asserts a reset signal when the supply voltage drops below a preset threshold, holding the reset active for a fixed delay after the voltage returns to a valid level.  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy  
- **Manual Reset Input:** Allows external pushbutton reset control  
- **Power-Fail Comparator:** Provides early warning of power loss  
- **No External Components Required:** Simplifies design  
- **Space-Saving 8-Pin SOIC Package**  

The MAX808LCSA is commonly used in embedded systems, industrial controls, and battery-powered applications requiring reliable power monitoring.
