Description and Introduction

Micropower Undervoltage Sensing Circuit The MC34164P-5 is a voltage monitor IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Undervoltage Detector  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Threshold Voltage (Vth):** 4.55V (fixed)  
- **Accuracy:** ±2%  
- **Quiescent Current:** 8µA (typical)  
- **Output Type:** Open-collector  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 3-Pin TO-92  

### **Descriptions:**  
The MC34164P-5 is designed to monitor power supply voltages and provide a reset signal when the voltage drops below a preset threshold (4.55V). It is commonly used in battery-powered systems, microprocessors, and other applications requiring voltage supervision.  

### **Features:**  
- **Fixed Threshold Voltage (4.55V)**  
- **Low Power Consumption**  
- **Open-Collector Output for Easy Interface**  
- **Wide Operating Voltage Range (1.0V to 5.5V)**  
- **High Accuracy (±2%)**  
- **Available in TO-92 Package**  

This IC ensures system reliability by preventing erratic operation during power-up, power-down, or brownout conditions.
