Description and Introduction

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821LUS-T is a microprocessor voltage monitor manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6µA (typical)  
- **Output Type:** Push-Pull Active-Low RESET  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX821LUS-T is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems when the supply voltage drops below a preset threshold. It ensures proper system operation during power-up, power-down, and brownout conditions.  

### **Features:**  
- **Low Power Consumption:** 6µA typical supply current  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **No External Components Required:** Simplifies design  
- **Small Form Factor:** Available in a SOT-23-3 package  
- **Guaranteed Reset Valid Down to VCC = 1V**  

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