Description and Introduction

5V Adjustable, CMOS, Step-Down Switching Regulator The MAX638AESA+ 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  
- **Category:** PMIC - Supervisors  
- **Type:** Simple Reset/Power-On Reset  
- **Number of Voltages Monitored:** 1  
- **Reset:** Active Low  
- **Output Type:** Push-Pull, Totem Pole  
- **Manual Reset:** No  
- **Watchdog Timer:** No  
- **Reset Timeout:** 140 ms (Typical)  
- **Voltage - Threshold:** 4.63V  
- **Operating Temperature:** -40°C to +85°C  
- **Package / Case:** 8-SOIC (0.154", 3.90mm Width)  
- **Packaging:** Tube  

### **Descriptions:**
The MAX638AESA+ is a precision voltage monitor designed to monitor a single power supply voltage. It asserts a reset signal when the supply voltage drops below a preset threshold (4.63V), ensuring proper system operation during power-up, power-down, or brownout conditions.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Supply Current:** Typically 15μA.  
- **Guaranteed Reset Valid Down to VCC = 1V.**  
- **No External Components Required.**  
- **Push-Pull RESET Output:** Eliminates the need for a pull-up resistor.  
- **Available in 8-Pin SOIC Package.**
