Description and Introduction

4-Pin, µP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821SUS+T is a voltage detector manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Detector  
- **Package:** SOT-23-3  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Threshold Voltage Options:** Factory-set (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Accuracy:** ±1.5% (typical)  
- **Quiescent Current:** 1.5µA (typical)  
- **Output Type:** Active-Low, Open-Drain  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX821SUS+T is a low-power voltage detector designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold. It is commonly used in battery-powered applications, microcontrollers, and power management systems.  

### **Features:**  
- **Ultra-Low Power Consumption:** 1.5µA typical quiescent current  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy  
- **Open-Drain Output:** Allows flexibility in interfacing with different logic levels  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **Small Package:** SOT-23-3 for space-constrained applications  
- **No External Components Required:** Simplifies circuit design  

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