Description and Introduction

Low-Cost レP Supervisory Circuits with Battery Backup The MAX703CSA is a low-power CMOS supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6µA (typical)  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX703CSA monitors system voltage and provides a reset signal to the microprocessor during power-up, power-down, or brownout conditions.  
- It includes a manual reset input for external triggering.  
- Designed for low-power applications, it ensures reliable system operation by preventing erratic behavior during voltage fluctuations.  

### **Features:**  
- **Low Power Consumption:** 6µA typical supply current.  
- **Adjustable or Fixed Reset Threshold:** Multiple voltage options available.  
- **Manual Reset Input:** Allows external reset control.  
- **Power-On Reset Delay:** Guarantees stable power before system start-up.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet for the MAX703CSA.
