Description and Introduction

CMOS, Micropower, Step-Up Switching Regulator The MAX630 is a microprocessor supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 1.9V, 2.7V, 3.1V, 4.65V, etc.)  
- **Reset Timeout Period:** Adjustable via external capacitor (default 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 5µA  
- **Output Type:** Active-low or active-high reset (depending on variant)  

### **Descriptions:**
- The MAX630 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 different reset threshold voltages to suit various applications.  

### **Features:**
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Adjustable Reset Timeout:** Allows customization via an external capacitor.  
- **Manual Reset Input:** Supports external push-button reset functionality.  
- **Small Package Options:** Available in 8-pin DIP, SOIC, and µMAX packages.  
- **No External Components Required:** For basic reset functionality (except for adjustable timeout).  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  

For exact part numbers and threshold options, refer to the MAX630 datasheet.
