Description and Introduction

4-Pin µP Voltage Monitors with Manual Reset Input The MAX811SEUS+T is a microprocessor reset circuit manufactured by **Maxim Integrated**.  

### **Specifications:**  
- **Type:** Voltage Monitor (μP Reset Circuit)  
- **Reset Threshold Options:** Factory-Set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Output Type:** Active-Low, Push-Pull  
- **Package:** SOT-143-4  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typ)  

### **Descriptions:**  
- Monitors system voltage and asserts a reset signal when the voltage falls below a preset threshold.  
- Ensures proper microprocessor initialization during power-up, power-down, or brownout conditions.  
- No external components required for operation.  

### **Features:**  
- **Low Power Consumption:** Minimal current draw in operation.  
- **Precision Voltage Monitoring:** Accurate reset threshold for reliable operation.  
- **Manual Reset Capability:** Some variants support an external reset input (not applicable to all models).  
- **Small Form Factor:** SOT-143 package for space-constrained applications.  
- **Wide Voltage Range:** Compatible with various logic levels (1.2V–5.5V).  

For exact threshold voltage and additional details, refer to the **Maxim Integrated datasheet**.

Application Scenarios & Design Considerations

4-Pin µP Voltage Monitors with Manual Reset Input

Alternative Part Number

  • TPS3808G01DBVR --: Adjustable supervisory circuit in SOT-23-5 with similar reset threshold and open-drain output, a common cross for MAX811 voltage monitors.
  • ADM811SARTZ-REEL --: Direct functional equivalent 4-pin microprocessor supervisor with 2.93V threshold and active-low reset, pin-compatible in SOT-143.
  • CAT811STBI-GT3 --: Low-cost 4-pin voltage supervisor with 2.93V reset threshold and active-low push-pull reset, suitable drop-in replacement for MAX811S.
  • TPS3808G33DBVR --: Pin-compatible voltage supervisor with adjustable delay and active-low reset, widely available and functionally similar to the MAX811 reset supervisor.
  • ADM811SARTZ-REEL7 --: Direct functional equivalent reset supervisor IC in SOT-23 package with active-low push-pull reset output, suitable drop-in replacement.
