Description and Introduction

3.3V-Input to Regulated 5V-Output Charge Pumps The MAX682ESA is a microprocessor (μP) voltage monitor manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (150mil)  
- **Type:** Voltage Monitor  
- **Number of Channels:** 1  
- **Voltage - Threshold:** 4.63V  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Timeout:** 140ms (min)  
- **Operating Temperature:** -40°C to +85°C  
- **Supply Voltage (Max):** 5.5V  
- **Supply Current:** 20μA (typical)  

### **Descriptions:**  
The MAX682ESA is a precision voltage monitor designed to ensure proper system operation by monitoring the power supply voltage. It asserts a reset signal when the supply voltage drops below a preset threshold (4.63V), ensuring a controlled system reset.  

### **Features:**  
- **Precision Voltage Monitoring:** Guarantees accurate reset threshold detection.  
- **Low Power Consumption:** Only 20μA typical supply current.
