Description and Introduction

4-Pin, µP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The **MAX822TUS+T** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX822TUS+T  
- **Package:** SOT-23-3  
- **Type:** Voltage Monitor / Supervisor  
- **Reset Threshold Voltage:** Adjustable or Fixed (specific value depends on variant)  
- **Operating Voltage Range:** Typically 1.2V to 5.5V  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Output Type:** Active-Low Reset  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX822TUS+T is a low-power microprocessor voltage monitor designed to ensure proper system operation during power-up, power-down, and brownout conditions. It provides a reset signal to the μP when the supply voltage falls below a preset threshold, preventing erratic behavior.  

### **Features:**  
- **Low Quiescent Current:** Typically 5μA (enhances battery life).  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Manual Reset Input:** Allows external pushbutton reset control (if applicable).  
- **Small Form Factor:** SOT-23-3 package for space-constrained applications.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Power-Fail Comparator:** Optional in some variants for early warning of power loss.  

For exact reset threshold values and other variant-specific details, refer to the official **Maxim Integrated datasheet**.
