Description and Introduction

Universal Voltage Monitor The MC33161 is a voltage monitor IC manufactured by ON Semiconductor (formerly Motorola).  

### **Manufacturer:**  
- **ON Semiconductor** (originally developed by Motorola)  

### **Specifications:**  
- **Operating Voltage Range:** 2.0V to 40V  
- **Quiescent Current:** 75µA (typical)  
- **Input Threshold Accuracy:** ±1.5%  
- **Temperature Range:** -40°C to +85°C  
- **Output Configuration:** Open-collector  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**  
- The MC33161 is a precision undervoltage/overvoltage monitor designed for automotive and industrial applications.  
- It features two independent comparators with a built-in 1.27V reference voltage.  
- The device monitors voltage levels and provides an output signal when the monitored voltage falls outside preset thresholds.  

### **Features:**  
- **Dual Comparator Design:** Allows monitoring of two separate voltage levels.  
- **Adjustable Thresholds:** External resistors set the trip points.  
- **Low Power Consumption:** Suitable for battery-operated systems.  
- **Wide Operating Voltage Range:** Supports 2.0V to 40V operation.  
- **Open-Collector Outputs:** Can interface with various logic levels.  
- **Built-in Hysteresis:** Prevents output oscillation near threshold points.  
- **ESD Protection:** Enhanced robustness for harsh environments.  

This IC is commonly used in power supply monitoring, battery management, and automotive systems.
