Description and Introduction

Microprocessor supervisory circuit. Reset threshold 4.38V. Active-low reset. Active-high reset. Manual reset input. The MAX825MEUK is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Microprocessor Supervisor  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically a few microamps)  

### **Descriptions:**  
The MAX825MEUK is a voltage monitor designed to ensure proper operation of microprocessors and digital systems. It monitors the power supply voltage and asserts a reset signal if the voltage falls below a preset threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset assertion even at very low voltages.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
