Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 3.08V The MAX811TEUS-T 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 (Analog Devices)  
- **Part Number:** MAX811TEUS-T  
- **Package:** SOT-143  
- **Type:** Voltage Monitor / Supervisor IC  
- **Number of Channels:** 1  
- **Reset Threshold Voltage Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (varies by suffix)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (typical)  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX811TEUS-T is a low-power μP reset circuit designed to monitor system voltage and provide a reset signal to the processor if the voltage falls below a specified threshold.  
- It ensures reliable system operation by preventing erratic behavior during power-up, power-down, or brownout conditions.  
- Available in a compact SOT-143 package, making it suitable for space-constrained applications.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures accurate reset triggering at the selected threshold.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset even at very low voltages.  
- **Push-Pull RESET Output:** Eliminates the need for an external pull-up resistor.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

For exact threshold voltage selection, refer to the suffix in the part number (e.g., MAX811**T**EUS-T corresponds to a specific threshold).  

(Note: Always verify datasheet details for precise application requirements.)
