Description and Introduction

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821RUS-T is a voltage detector manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Type:** Voltage Detector  
- **Output Type:** Active-Low, Open-Drain  
- **Number of Channels:** 1  
- **Threshold Voltage Options:** Factory-Set (e.g., 4.65V, 4.38V, 3.08V, etc., depending on variant)  
- **Accuracy:** ±1.5% (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5µA (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX821RUS-T is a precision voltage detector designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold. It features an open-drain output and low power consumption, making it suitable for battery-powered applications.  

### **Features:**  
- Low quiescent current (5µA typical)  
- Factory-trimmed threshold voltage  
- Open-drain output for easy interfacing  
- Wide operating voltage range (1.2V to 5.5V)  
- Small SOT-23-3 package  
- No external components required  

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

Description and Introduction

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821RUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** SOT-23-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**  
The MAX821RUS-T monitors system voltages and provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Low Power Consumption:** Only 6μA typical quiescent current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Precision Voltage Monitoring:** ±1.5% reset threshold accuracy.  
- **Manual Reset Input:** Allows external reset control.  
- **Small Form Factor:** Available in a compact SOT-23-4 package.  
- **No External Components Required:** Simplifies design.  

This information is strictly based on the manufacturer's datasheet.
