Description and Introduction

Micropower Undervoltage Sensing Circuit The MC33164P-5 is a voltage monitor IC manufactured by Motorola. Below are its key specifications, descriptions, and features based on available factual information:

### **Specifications:**  
- **Manufacturer:** Motorola  
- **Type:** Undervoltage Monitor IC  
- **Package:** 5-Pin TO-92  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Threshold Voltage (Vth):** 4.55V (nominal)  
- **Hysteresis:** 150mV (typical)  
- **Output Type:** Open Collector  
- **Quiescent Current:** 8µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MC33164P-5 is designed to monitor power supply voltages and provide a reset signal when the voltage drops below a preset threshold (4.55V). It ensures proper system operation by preventing erratic behavior during undervoltage conditions.  

### **Features:**  
- Precision undervoltage detection  
- Low power consumption  
- Open-collector output for easy interfacing  
- Built-in hysteresis for noise immunity  
- Wide operating voltage range (1.0V to 5.5V)  
- Suitable for battery-powered and portable applications  

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