Description and Introduction

Low-Cost, uP Supervisory Circuits The MAX705CPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX705CPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Reset Threshold Options:** 4.40V, 4.65V, or 4.90V (factory-set)  
- **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)  
- **Power-On Reset (POR):** Ensures valid reset at power-up  

### **Descriptions:**
- The MAX705CPA monitors power supply voltage and provides a reset signal to the microprocessor if the voltage drops below a preset threshold.  
- It includes a watchdog timer to detect software lockups and a manual reset input for external system resets.  
- Designed for reliability in microprocessor-based systems, ensuring proper initialization during power-up or brownout conditions.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Watchdog Timer:** Prevents system lockups by requiring periodic toggling.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Power Consumption:** Typically 50μA supply current.  
- **Power-On Reset (POR) Circuitry:** Guarantees reset during power-up.  
- **Space-Saving 8-Pin Package:** Suitable for compact designs.  

This device is commonly used in embedded systems, industrial controls, and automotive applications where stable voltage monitoring is critical.  

(Note: Always refer to the official datasheet for detailed technical specifications.)
