Description and Introduction

Low-Cost Microprocessor Supervisory Circuits with Battery Backup The MAX703ESA+ is a low-power CMOS supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5µA (typical)  
- **Reset Threshold Options:** Factory-set (2.63V, 2.93V, 3.08V, 4.38V, 4.63V) or adjustable via external resistors  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- Monitors system voltage and generates a reset signal when the voltage falls below a preset threshold.  
- Ensures proper microprocessor/microcontroller operation during power-up, power-down, or brownout conditions.  
- Features a manual reset input for external system control.  

### **Features:**  
- Low power consumption (5µA typical).  
- Precision voltage monitoring with factory-set or adjustable thresholds.  
- Guaranteed reset output valid down to VCC = 1V.  
- Manual reset input for external triggering.  
- No external components required for fixed threshold versions.  
- Space-saving 8-pin SOIC package.  

This device is commonly used in battery-powered systems, embedded controllers, and critical microprocessor-based applications.
