Description and Introduction

Microprocessor and non-volatile metory supervisory circuit. Reset threshold 4.62V. Reset and low-line threshold accuracy +-2% The MAX820LCSE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX820LCSE  
- **Package:** 16-SOIC (150 mil)  
- **Type:** Microprocessor Supervisor  
- **Voltage - Threshold:** 4.65V (adjustable)  
- **Number of Voltages Monitored:** 1  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Timeout:** 140ms (min)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Supply Voltage (Vcc):** 1V to 5.5V  

### **Descriptions:**
- The MAX820LCSE is a precision voltage monitor designed to ensure proper system operation in microprocessor-based applications.  
- It provides a reset signal to the μP when the supply voltage drops below a preset threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.  
- Features an adjustable or fixed threshold voltage option (factory-set or user-programmable).  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Adjustable Threshold:** Allows customization for different applications.  
- **Low Power Consumption:** Ideal for battery-powered systems.  
- **Push-Pull RESET Output:** No external pull-up resistor required.  
- **Guaranteed Reset Valid Down to Vcc = 1V:** Ensures proper operation even at low voltages.  
- **140ms (min) Reset Timeout:** Prevents premature system restart.  

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