Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 4.38V The MAX811MEUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor / Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (selectable)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-143-4  

### **Descriptions:**
The MAX811MEUS-T is a low-power microprocessor voltage monitor designed to ensure proper system operation during power-up, power-down, and brownout conditions. It asserts a reset signal when the supply voltage drops below a preset threshold, preventing erratic behavior in μP-based systems.  

### **Features:**
- **Low Power Consumption:** Only 5μA typical supply current.  
- **Precision Voltage Monitoring:** Accurate threshold detection with factory-set options.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **Push-Pull RESET Output:** No external pull-up resistor needed.  
- **Small Form Factor:** Available in a compact SOT-143-4 package.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.  

(Note: Always refer to the official datasheet for detailed technical specifications.)
