Description and Introduction

Very Low Supply Current 3−Pin Microprocessor Reset Monitors The MAX809TTRG is a microprocessor reset circuit manufactured by ONSEMI. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Active-Low Reset (Open-Drain or Push-Pull)  
- **Package:** SOT-23-3  

### **Descriptions:**  
- The MAX809TTRG is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems during power-up, power-down, or brownout conditions.  
- It ensures proper system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**  
- **Low Quiescent Current:** 8µA (typ)  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy  
- **No External Components Required:** Simplifies design  
- **Available in Multiple Threshold Voltages:** Supports various system voltages  
- **Small Form Factor:** SOT-23-3 package for space-constrained applications  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to ONSEMI's official documentation.

Application Scenarios & Design Considerations

Very Low Supply Current 3−Pin Microprocessor Reset Monitors

Alternative Part Number

  • ADM809TARTZ-REEL --: Pin-compatible supervisor with the same T-threshold and active-low reset, widely available and a direct functional drop-in.
  • TPS3809T30DBVR --: 3-pin voltage supervisor with matching threshold and reset polarity, low power and common in the same applications.
  • MCP809T-315E/TT --: Similar reset supervisor with comparable threshold and active-low output, suitable as a cross-manufacturer alternative.
  • APX809-31SAG-7 --: Pin-compatible 3-pin voltage supervisor with 3.08V threshold and active-low reset, direct functional replacement for MAX809T in SOT-23.
  • TPS3809L30DBVR --: Low-power 3-pin SOT-23 voltage supervisor with 3.0V threshold and active-low reset, suitable drop-in alternative for supply monitoring.
