Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX825MEUK-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Series:** MAX825  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 4.63V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**  
The MAX825MEUK-T monitors microprocessor power supplies, providing a reset signal if the supply voltage drops below a preset threshold. It ensures proper system operation by holding the reset signal until the supply stabilizes.  

### **Features:**  
- Low power consumption (6μA typical)  
- Precision voltage monitoring  
- Manual reset input  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required (for fixed threshold versions)  
- Available in a small SOT-23-5 package  

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