Description and Introduction

4-Pin P 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:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Package:** SOT-23-3  
- **Type:** Voltage Monitor/Supervisory IC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (min)  
- **Quiescent Current:** 5μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX822TUS-T is a low-power voltage monitor designed to ensure proper system operation by monitoring the power supply voltage and generating a reset signal when the voltage falls below a preset threshold. It is commonly used in battery-powered and embedded systems to prevent erratic behavior during power-up, power-down, or brownout conditions.

### **Features:**
- **Low Power Consumption:** Ultra-low quiescent current (5μA typical).  
- **Precision Voltage Monitoring:** Ensures reliable reset generation.  
- **Manual Reset Input (Optional):** Some variants support an external reset trigger.  
- **Small Form Factor:** Available in a compact SOT-23-3 package.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable reset assertion even at low voltages.  

For exact reset threshold values and additional details, refer to the official datasheet from Maxim Integrated (Analog Devices).
