Description and Introduction

Microprocessor Supervisory Circuits The MAX802LESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX802LESA+  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (specific threshold depends on variant)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some versions)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically 5µA)  

### **Descriptions:**  
The MAX802LESA+ is designed to monitor system power supplies and provide a reset signal to a 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 Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows for external reset control.  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** Available in an 8-pin SOIC package.  
- **Guaranteed Reset Assertion:** Prevents false triggering.  

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