Description and Introduction

4-Pin µP Voltage Monitors with Manual Reset Input The MAX811SEUS+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Part Number:** MAX811SEUS+  
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor/Supervisor  
- **Package:** SOT-143  
- **Number of Pins:** 4  
- **Reset Threshold Voltage:** 2.93V (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (minimum)  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX811SEUS+ monitors the power supply voltage of a microprocessor or microcontroller 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:** Typically 5μA supply current.  
- **Manual Reset Input:** Allows external reset control.  
- **No External Components Required:** Simplifies design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset assertion even at low voltages.  
- **Small Form Factor:** SOT-143 package for space-constrained applications.  

This information is based on the manufacturer's datasheet. For detailed specifications, refer to the official documentation.

Application Scenarios & Design Considerations

4-Pin µP Voltage Monitors with Manual Reset Input

Alternative Part Number

  • TPS3808G01DBVR --: Adjustable-threshold supervisor in SOT-23-5 with similar reset functionality and active-low push-pull output, widely available and pin-compatible in function.
  • ADM811SARTZ-REEL7 --: Direct functional equivalent voltage supervisor with 2.93V threshold and active-low reset, offered in SOT-23 package as a drop-in style replacement.
  • CAT811STBI-GT3 --: Low-cost 5-pin SOT-23 voltage supervisor with comparable threshold and reset output, suitable as a second-source alternative.
