Description and Introduction

PLASTIC ENCAPSULATED DEVICES The MAX811TEUS is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** SOT-143  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage:** 2.63V (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX811TEUS is designed to monitor the power supply voltage of a microprocessor or microcontroller. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system initialization upon power-up or brownout conditions.  

### **Features:**
- **Low Power Consumption:** Typically 5μA supply current  
- **Precision Voltage Monitoring:** Ensures reliable reset operation  
- **No External Components Required:** Simplifies circuit design  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset assertion even at very low voltages  
- **Push-Pull RESET Output:** No external pull-up resistor needed  
- **Small Form Factor:** Available in a SOT-143 package for space-constrained applications  

This information is based solely on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

PLASTIC ENCAPSULATED DEVICES

Alternative Part Number

  • TPS3808G01DBVR --: Adjustable-threshold supervisor in SOT-23-5 with similar reset function and open-drain output, widely available and pin-compatible in function.
  • ADM811TARTZ-REEL --: Direct functional equivalent of the MAX811T with 3.08V threshold and active-low reset, from a different series and manufacturer.
  • MCP131T-315E/TO --: Low-cost voltage supervisor with 3.15V threshold and active-low reset, suitable drop-in functional replacement in TO-92/SOT-23 packages.
  • MCP131T-315E/TT --: Low-cost voltage supervisor with ~3.15V threshold and active-low reset in SOT-23, suitable drop-in alternative.
