Description and Introduction

5V/3.3V/3V/Adjustable, High-Efficiency, Low IQ, Step-Down DC-DC Converters The MAX653ESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-Fail Comparator:** No  

### **Descriptions:**  
The MAX653ESA is a low-power microprocessor supervisory circuit designed to monitor system voltage and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures proper system operation by holding the μP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Low Supply Current:** 6μA (typical) for power efficiency.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Precision Voltage Monitoring:** ±1.5% reset threshold accuracy.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Guaranteed Reset Output:** Valid down to VCC = 1V.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained applications.  
- **No External Components Required:** Simplifies design.  

This information is based solely on the manufacturer's datasheet for the MAX653ESA.
