Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 2.93V The MAX811SEUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX811SEUS-T  
- **Type:** Voltage Monitor / Supervisor  
- **Package:** SOT-143-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.63V, 2.93V, 3.08V, 4.38V (factory-set)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**
- The MAX811SEUS-T monitors system voltage levels and provides a reset signal to the microprocessor when the voltage drops below a preset threshold.  
- It ensures proper system operation by preventing erratic behavior during power-up, power-down, or brownout conditions.  
- Available in a small SOT-143-4 package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Power Consumption:** Only 5μA typical supply current.  
- **Precision Voltage Monitoring:** Factory-trimmed threshold options.  
- **Manual Reset Input:** Allows external reset control.  
- **Guaranteed Reset Output Valid Down to VCC = 1V.**  
- **No External Components Required:** Simplifies circuit design.  
- **Power-On Reset (POR) Generation:** Ensures proper startup.  

This device is commonly used in embedded systems, microcontrollers, and other applications requiring reliable power monitoring.
