Description and Introduction

Low-Cost, µP Supervisory Circuits The MAX707CPA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (4.40V, 4.00V, 3.08V, 2.93V, 2.63V, 2.32V)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** 1.6s timeout (typical)  

### **Descriptions:**
The MAX707CPA+ is designed to monitor power supply voltages in microprocessor-based systems. It provides reset signals to the μP during power-up, power-down, and brownout conditions. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset generation for supply voltages.  
- **Adjustable or Fixed Reset Thresholds:** Multiple options for different applications.  
- **Watchdog Timer:** Helps recover from system crashes.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures proper reset even at low voltages.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations
