Description and Introduction

Microprocessor Voltage Monitors with Programmable Voltage Detection The MAX8211ESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable (external capacitor) or fixed (200ms typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  
- **Output Type:** Active-low RESET  

### **Descriptions:**
The MAX8211ESA is a low-power voltage monitor designed to ensure proper system operation in microprocessor-based applications. It monitors the power supply voltage and generates a reset signal if the voltage falls below a preset threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**
- **Low Power Consumption:** Only 6μA typical quiescent current.  
- **Adjustable Reset Threshold:** Can be set using external resistors.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Guaranteed Reset Output Valid Down to VCC = 1V.**  
- **No External Components Required for Fixed Threshold Version.**  
- **Small Footprint:** Available in an 8-pin SOIC package.  

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