Description and Introduction

Universal Voltage Monitor The MC33161 is a voltage monitor IC manufactured by ON Semiconductor. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 3.0V to 28V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 75µA (typical)  
- **Output Sink Current:** 20mA (minimum)  
- **Input Threshold Accuracy:** ±1.5% (over temperature)  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**
- The MC33161 is a dual over/under voltage detector designed for monitoring power supply voltages in automotive, industrial, and consumer applications.  
- It includes two independent comparators with built-in voltage references for precise monitoring.  
- The device provides an open-drain output that can be used to signal a fault condition.  

### **Features:**
- **Dual Voltage Monitoring:** Capable of monitoring two separate voltage rails.  
- **Adjustable Thresholds:** External resistors allow customization of over/under voltage trip points.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Built-in Hysteresis:** Prevents output oscillation near the threshold.  
- **Wide Operating Voltage Range:** Suitable for 3V to 28V systems.  
- **Open-Drain Output:** Allows flexible interfacing with other logic circuits.  

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

Application Scenarios & Design Considerations

Universal Voltage Monitor

Alternative Part Number

  • TL7705ACP --: Single voltage supervisor with similar supply-voltage monitoring function and open-collector reset output; widely available and pin-compatible in most supervisor applications.
  • MC34064P --: Undervoltage sensing circuit from a different series that provides comparable voltage monitoring and reset generation for microprocessor systems.
  • MAX809R --: Compact 3-pin microprocessor reset supervisor offering similar reset threshold monitoring, suitable as a functional replacement in many designs.
  • MC34064P-5 --: Undervoltage sensing circuit in the same family lineage but a different series, commonly used as a drop-in style supply monitor alternative.
