Description and Introduction

5V Fixed/Adjustable Output, Step-Up Switching Regulators The MAX631AESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (at +25°C)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  
- **Low Quiescent Current:** 5μA (typ)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR) Circuitry:** Yes  
- **Output Type:** Active-low, push-pull  

### **Descriptions:**  
The MAX631AESA+ monitors system voltage and provides a reset signal to the microprocessor if the supply voltage drops below a preset threshold. It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Capability:** Allows external reset triggering.  
- **Wide Operating Voltage Range:** Supports various system voltages.  
- **No External Components Required:** Simplifies design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures robust operation.  

This device is commonly used in embedded systems, industrial controls, and portable electronics where reliable power monitoring is critical.
