Description and Introduction

Low-Cost レP Supervisory Circuits with Battery Backup The MAX703EPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (for 5V operation)  
- **Reset Timeout Period:** Adjustable (typically 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (programmable timeout)  
- **Power-On Reset (POR):** Yes  

### **Descriptions:**
The MAX703EPA is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal if the supply voltage drops below a specified threshold. It includes a watchdog timer to detect software crashes and a manual reset input for user-initiated resets.  

### **Features:**
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Adjustable Watchdog Timer:** Prevents system lockups by requiring periodic toggling.  
- **Manual Reset Capability:** Allows external push-button reset functionality.  
- **Low Power Consumption:** Typically 50μA supply current.  
- **Guaranteed Reset Output:** Valid down to VCC = 1V.  
- **Space-Saving Package:** Available in an 8-pin DIP for easy integration.  

This information is strictly factual and sourced from the manufacturer's datasheet.
