Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 4.63V The MAX811LEUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX811LEUS-T  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Package:** SOT-143-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Factory-Set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  
- **Output Type:** Active-Low, Push-Pull  

### **Descriptions:**
- The MAX811LEUS-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.  
- The device features a manual reset input for external control.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Quiescent Current:** 6μA (typical) for power efficiency.  
- **Manual Reset Input:** Allows external system reset control.  
- **No External Components Required:** Simplifies design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset assertion 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 information is based solely on the manufacturer's datasheet and technical documentation.
