Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX825LEUK+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. 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 Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  

### **Descriptions:**  
The MAX825LEUK+T monitors system voltage levels 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:** Only 5µA typical supply current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Precision Voltage Monitoring:** ±1.5% reset threshold accuracy.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Guaranteed Reset Output Valid Down to VCC = 1V.**  
- **Small Form Factor:** Available in a compact SOT-23-5 package.  

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