Description and Introduction

CMOS Micropower Step-UP Switching Regulator The MAX630ESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX630ESA  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Type:** μP Supervisory Circuit  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory preset (1.9V, 2.7V, 3.1V, 4.2V, etc.) or adjustable  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**
- The MAX630ESA monitors microprocessor power supplies and generates a reset signal if the voltage drops below a preset threshold.  
- It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  
- Available in fixed or adjustable threshold versions for flexibility in different applications.  

### **Features:**
- **Low Power Consumption:** Ultra-low quiescent current (5μA typical).  
- **Precision Voltage Monitoring:** Accurate reset threshold detection.  
- **Manual Reset Input:** Allows external reset control.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  
- **Temperature Stability:** Reliable operation across industrial temperature ranges.  

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