Description and Introduction

Microprocessor Voltage Monitor with The ICL7665ACSA is a dual over/under voltage detector manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** ICL7665ACSA  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.5V to 16V  
- **Quiescent Current:** 50µA (typical)  
- **Temperature Range:** 0°C to +70°C (commercial grade)  
- **Output Configuration:** Open-drain  
- **Detection Accuracy:** ±2% (typical)  
- **Threshold Voltage Options:** Fixed or adjustable via external resistors  

### **Descriptions:**
The ICL7665ACSA is a dual voltage monitor designed to detect overvoltage and undervoltage conditions in power supply systems. It provides two independent comparators with open-drain outputs, making it suitable for battery monitoring, power supply sequencing, and system protection applications.  

### **Features:**
- **Dual Voltage Monitoring:** Two independent detectors for overvoltage and undervoltage.  
- **Adjustable Thresholds:** Can be set using external resistors or fixed internally.  
- **Low Power Consumption:** Typically 50µA quiescent current.  
- **Wide Operating Voltage Range:** 1.5V to 16V.  
- **Open-Drain Outputs:** Allows flexible interfacing with other logic levels.  
- **High Accuracy:** ±2% threshold detection accuracy.  
- **Power-On Reset Delay:** Ensures stable operation at startup.  

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

Application Scenarios & Design Considerations

Microprocessor Voltage Monitor with

Alternative Part Number

  • MAX6341CSA --: Voltage monitor/supervisor in the same function class with similar SOIC-8 package and comparator-based threshold detection, suitable as a functional replacement.
  • LTC2912CMS8-1 --: Over/under voltage monitor with adjustable thresholds and open-drain outputs, matching the dual comparator supervisor role of the original.
  • TPS3700DDCR --: Window voltage supervisor with dual comparators and adjustable thresholds, offering a comparable monitoring function in a small package.
  • MAX6457CSA --: Voltage monitor/supervisor in the same family with similar dual-threshold detection function and SOIC-8 package, direct functional replacement.
  • MC33164D-5 --: Micropower undervoltage/voltage supervisor IC with similar monitoring role and low current consumption, suitable as a functional substitute.
  • TL7705ACD --: Supply voltage supervisor in SOIC-8 with adjustable/reset monitoring behavior, a common alternative when the exact ICL7665 function is unavailable.
  • MAX6457UKD0A+T --: Dual voltage monitor/supervisor with similar over/under-voltage detection function and adjustable thresholds, pin-compatible style in small package.
  • LTC2912IDDB-1#TRMPBF --: Dual supply voltage monitor offering comparable over/under-voltage window detection and open-drain outputs, suitable functional replacement.
  • MAX6457AUT-T --: Voltage monitor/supervisor with similar over/under-voltage detection function, different series naming, good functional match.
  • LTC2912IMS8-1 --: Dual voltage supervisor with adjustable thresholds, comparable to the ICL7665 dual comparator function, different prefix and series.
