Description and Introduction

UnderVoltage Sensing Circuit The **MC34064P-5RA** is a power-on reset (POR) IC manufactured by **ON Semiconductor**.  

### **Specifications:**  
- **Function:** Monitors power supply voltage and generates a reset signal when the voltage drops below a threshold.  
- **Reset Threshold Voltage:** 4.55V (typical) for the -5 variant (5V operation).  
- **Operating Voltage Range:** 1.2V to 10V.  
- **Output Type:** Active-low open-drain (requires a pull-up resistor).  
- **Reset Pulse Width:** Typically 100ms (minimum).  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 3-pin TO-92.  

### **Descriptions & Features:**  
- Designed for microprocessor and microcontroller reset applications.  
- Ensures proper system initialization by holding the reset signal until the supply voltage stabilizes.  
- Low quiescent current consumption.  
- Built-in hysteresis to prevent erratic reset signals during voltage fluctuations.  
- Suitable for battery-powered and industrial applications.  

For detailed electrical characteristics and application notes, refer to the official **ON Semiconductor datasheet**.
