Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 2.925V. Active-low reset. Watchdog input. Backup-battery switch. Power-fail threshold accuracy +-2%. Power-fail comparator. Reset window +-2% The MAX802SCSA 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:** MAX802SCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Type:** Voltage Monitor / Supervisor  
- **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)  
- **Quiescent Current:** 5μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX802SCSA monitors system voltage and provides a reset signal to the microprocessor when the voltage falls below a preset threshold.  
- It ensures proper system operation by holding the μP in reset until the supply voltage stabilizes.  
- Available in fixed threshold voltages for different applications.  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current.  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR):** Ensures proper system initialization.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  

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