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**.

Application Scenarios & Design Considerations

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset

Alternative Part Number

  • ADM823MYRJZ-R7 --: Pin-compatible supervisory circuit with similar reset threshold and watchdog function; ADI acquired Maxim, so this is a direct functional equivalent.
  • TPS3808G01DBVR --: Adjustable-threshold supervisor with watchdog and manual reset in SOT-23, suitable replacement for supply monitoring applications.
  • MCP1316MT-29LE/OT --: Low-power voltage supervisor with watchdog and manual reset in SOT-23-5, offering comparable functionality for 3V systems.
  • ADM823SYRJZ-R7 --: Direct pin-compatible supervisor with manual reset and watchdog in SOT-23-5, close match to the MAX823 feature set.
  • MCP1316MT-29FE/OT --: Low-power voltage supervisor with reset and watchdog in SOT-23-5, suitable drop-in style replacement for monitoring 3V/5V rails.
