Description and Introduction

4-Pin, µP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821SUS is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 5μA  

### **Descriptions:**  
The MAX821SUS is a low-power supervisory circuit designed to monitor system power supplies in microprocessor-based applications. It ensures reliable operation by generating a reset signal when the supply voltage drops below a specified threshold. The device is suitable for battery-powered and low-voltage systems due to its wide operating range and low current consumption.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset generation at a preset threshold.  
- **Low Quiescent Current:** Ideal for battery-operated applications.  
- **Wide Operating Voltage Range:** Supports 1.0V to 5.5V systems.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Adjustable or Fixed Reset Timeout:** Configurable for different system requirements.  
- **Small Package (SOIC):** Space-efficient for compact designs.

Description and Introduction

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

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Voltage Detector / Supervisor IC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Threshold Accuracy:** ±1.5% (typical)  
- **Output Type:** Active-Low Reset  
- **Reset Timeout Period:** Adjustable (external capacitor) or fixed (depending on variant)  
- **Quiescent Current:** Typically 5µA (low power consumption)  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade)  
- **Package:** SOT-23 (3-pin or 5-pin, depending on variant)  

### **Descriptions:**  
The MAX821SUS is a precision voltage detector designed to monitor system voltages and provide a reset signal when the supply voltage falls 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:** Ideal for battery-powered applications.  
- **Precision Threshold Detection:** Ensures reliable monitoring.  
- **Adjustable or Fixed Reset Timeout:** Configurable for different applications.  
- **Small Form Factor:** Available in compact SOT-23 packages.  
- **Industrial Temperature Range:** Suitable for harsh environments.
