Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX824SEXK+ 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  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage:** Adjustable or Fixed (depends on variant)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some models)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** Typically 5µA (low power consumption)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**
The MAX824SEXK+ monitors system voltage levels and provides a reset signal to the microprocessor when the voltage falls below a preset threshold. It ensures reliable system operation by preventing erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**
- **Low Power Consumption:** Ultra-low quiescent current (5µA typical).  
- **Precision Voltage Monitoring:** Ensures accurate reset threshold detection.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Compact Package:** Available in a small SOT23-5 package for space-constrained applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.
