Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The **MAX823MEUK+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 factual information from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MAXIM (now Analog Devices)**  

### **Description:**  
The MAX823MEUK+T is a precision voltage monitor designed to monitor system power supply voltages in microprocessor-based systems. It ensures proper system operation by providing a reset signal to the μP during power-up, power-down, or brownout conditions.  

### **Key Features:**  
1. **Voltage Monitoring:**  
   - Monitors **3V, 3.3V, and 5V** power supplies.  
   - Adjustable or fixed threshold options (depending on variant).  

2. **Reset Output:**  
   - Active-low (**RESET**) or active-high (**RESET**) reset output.  
   - Guaranteed reset valid for **VCC ≥ 1V**.  

3. **Low Power Consumption:**  
   - **5μA (typical)** supply current.  

4. **Manual Reset Input:**  
   - Includes a manual reset (**MR**) input for external pushbutton control.  

5. **Watchdog Timer (if applicable):**  
   - Some variants include a watchdog timer (not confirmed for this exact part number).  

6. **Packaging:**  
   - **SOT23-5** package.  

7. **Operating Temperature Range:**  
   - **-40°C to +85°C (Industrial Grade)**.  

8. **Applications:**  
   - Microprocessor (μP) and microcontroller (μC) systems.  
   - Embedded systems, industrial controls, and power management.  

### **Note:**  
- The **"MEUK+T"** suffix indicates the SOT23-5 package with tape-and-reel packaging.  
- For exact threshold voltages and additional features, refer to the official datasheet from **Maxim Integrated (Analog Devices)**.  

This information is strictly based on the manufacturer's specifications. For detailed electrical characteristics, refer to the **MAX823MEUK+T datasheet**.

Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX823MEUK+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Key Specifications:**  
- **Supply 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)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**  
The MAX823MEUK+T monitors system voltage and provides a reset signal to the microprocessor if the voltage falls below a preset threshold. It ensures proper system operation during power-up, power-down, and brownout conditions.  

### **Features:**  
- Low quiescent current (5μA typical)  
- Manual reset input  
- Guaranteed reset valid down to VCC = 1V  
- No external components required (for fixed threshold versions)  
- Space-saving SOT23-5 package  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications.
