Description and Introduction

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The **MAX821MUS-T** is a voltage detector manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Voltage Detector / Supervisor IC  
- **Package:** SOT-23-3 (US)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Threshold Voltage Options:** Factory-set (e.g., 4.63V, 4.38V, etc., depending on variant)  
- **Accuracy:** ±1.5% typical  
- **Quiescent Current:** 5µA (typical)  
- **Output Type:** Active-Low Reset (Open-Drain)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX821MUS-T is a micropower voltage detector designed to monitor system voltage levels. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system initialization. It is commonly used in battery-powered devices, microcontrollers, and embedded systems.  

### **Features:**  
- **Low Power Consumption:** 5µA typical quiescent current.  
- **Precision Monitoring:** ±1.5% threshold accuracy.  
- **Open-Drain Output:** Allows flexible interfacing with other logic.  
- **Wide Voltage Range:** Operates from 1.2V to 5.5V.  
- **Small Form Factor:** SOT-23-3 package for space-constrained designs.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  

For exact threshold voltage options, refer to the manufacturer's datasheet for the specific suffix (e.g., MAX821MUS+T may have different thresholds).  

(Note: Always verify details with the official datasheet as specifications may vary by variant.)
