Description and Introduction

MICROPOWER UNDERVOLTAGE SENSING CIRCUITS The **MC33164D-5** is a voltage monitor IC manufactured by **ON Semiconductor**.  

### **Specifications:**  
- **Type:** Undervoltage Monitor  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Threshold Voltage (Vth):** 4.55V (fixed for MC33164D-5)  
- **Hysteresis:** Typically 150mV  
- **Output Type:** Open Collector  
- **Output Current (Sink):** 10mA (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- Designed for monitoring power supply voltages in automotive, industrial, and consumer applications.  
- Provides a reset signal when the supply voltage drops below the threshold.  
- Features an open-drain output that requires an external pull-up resistor.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable system reset.  
- **Low Quiescent Current:** Typically 8µA.  
- **Wide Operating Voltage Range:** Supports various power supply levels.  
- **Built-in Hysteresis:** Prevents output oscillation near the threshold.  
- **Open-Collector Output:** Allows flexible interfacing with different logic levels.  

This IC is commonly used in power management circuits to ensure proper system operation under varying voltage conditions.
