Description and Introduction

Microprocessor Voltage Monitors with Programmable Voltage Detection The MAX8211CPA is a microprocessor voltage monitor manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8211CPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5µA (typical)  
- **Output Type:** Active-Low Reset (open-drain)  

### **Descriptions:**
The MAX8211CPA is a low-power microprocessor voltage monitor designed to ensure proper system operation by monitoring the power supply voltage. It generates a reset signal when the supply voltage falls below a preset threshold, preventing erratic behavior in microprocessors or digital systems. The reset output remains asserted for a fixed delay after the supply voltage returns to an acceptable level, ensuring stable operation.

### **Features:**
- **Low Power Consumption:** Only 5µA typical quiescent current.  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy.  
- **Adjustable Reset Timeout:** Configurable via an external capacitor.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Small Footprint:** Available in an 8-pin PDIP package.  
- **No External Components Required:** For fixed threshold operation.  

This device is commonly used in battery-powered systems, embedded controllers, and other applications requiring reliable power supply monitoring.
