Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 2.63V The MAX811REUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor / Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Threshold Voltage:** 2.63V (for MAX811REUS-T)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-143-4  

### **Descriptions:**  
The MAX811REUS-T monitors the power supply voltage of a microprocessor (μP) or microcontroller (μC) and asserts a reset signal when the voltage drops below a preset threshold. It ensures proper system operation by holding the reset signal until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Only 5μA typical quiescent current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset assertion even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  
- **Push-Pull RESET Output:** Eliminates the need for a pull-up resistor.  
- **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.
