Description and Introduction

4-Pin µP Voltage Monitors with Manual Reset Input The MAX811SEUS is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** SOT-143-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically a few microamps)  

### **Descriptions:**
- The MAX811SEUS monitors system voltage and provides a reset signal to the microprocessor when the voltage falls below a preset threshold.  
- It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  
- Available in a small SOT-143-4 package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Power Consumption:** Minimizes battery drain in portable applications.  
- **Manual Reset Input:** Allows for external reset control.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  
- **Hysteresis on Threshold Voltage:** Prevents erratic reset signals due to noise.  

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

(Note: For exact threshold voltage and other variant-specific details, refer to the official Maxim datasheet.)
