Description and Introduction

Microprocessor supervisory circuit. Reset threshold 3.08V. Active-low reset. Watchdog input. Manual reset input. The MAX823TEUK is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Supply Current:** 3.5μA (typ)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX823TEUK monitors system voltage levels and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It ensures proper system operation during power-up, power-down, and brownout conditions.  

### **Features:**
- **Low Power Consumption:** 3.5μA typical supply current  
- **Precision Voltage Monitoring:** Adjustable or factory-set reset thresholds  
- **Manual Reset Input:** Allows for external reset control  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **Guaranteed Reset Output Valid Down to VCC = 1V**  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable voltage monitoring is critical.

Description and Introduction

Microprocessor supervisory circuit. Reset threshold 3.08V. Active-low reset. Watchdog input. Manual reset input. The MAX823TEUK 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  
- **Type:** Microprocessor Supervisor  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or factory-set (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**
The MAX823TEUK monitors system voltage and provides a reset signal to the microprocessor when the 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:** Minimal current draw (6μA typical).  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **No External Components Required:** Simplifies circuit design.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable voltage monitoring is critical.
