Description and Introduction

Microprocessor Voltage Monitor with The ICL7665BCPA is a dual over/under voltage detector manufactured by Harris Semiconductor. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 16V  
- **Quiescent Current:** 60µA (typical)  
- **Output Configuration:** Open-drain  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The ICL7665BCPA is designed to monitor two independent voltage thresholds (over-voltage and under-voltage) for power supply supervision.  
- It features two comparators with built-in voltage references, providing precise detection of voltage deviations.  
- The open-drain outputs allow flexible interfacing with other logic circuits.  

### **Features:**  
- **Dual Voltage Monitoring:** Independently detects over-voltage and under-voltage conditions.  
- **Adjustable Thresholds:** External resistors set the trip points for each comparator.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Supply Range:** Operates from 1.2V up to 16V.  
- **Open-Drain Outputs:** Can be pulled up to a different voltage level for system compatibility.  
- **Built-in Hysteresis:** Prevents output oscillation near threshold points.  

This device is commonly used in power management, battery monitoring, and system protection circuits.
