Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The **MAX823TEUK-T** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Series:** MAX823  
- **Package:** SOT-23-5  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage Options:** Adjustable or Fixed (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** Typically 140ms (minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX823TEUK-T is a low-power μP supervisory circuit designed to monitor system voltages and provide a reset signal to the microprocessor during power-up, power-down, or brownout conditions. It ensures reliable system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**
- **Low Power Consumption:** 5μA typical supply current.  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **No External Components Required:** Simplifies design.  
- **Push-Pull RESET Output:** Active-low reset signal.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications.  

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

(Note: For exact threshold voltage options and detailed electrical characteristics, refer to the official datasheet.)
