Description and Introduction

MicroPower UnderVoltage Sensing Circuit The MC34164P-005 is an undervoltage sensing circuit manufactured by Motorola. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Undervoltage Sensing Circuit  
- **Package:** 3-Pin TO-92  
- **Operating Voltage Range:** 1.0V to 24V  
- **Threshold Voltage (Typical):** 4.65V (for MC34164P-005 variant)  
- **Hysteresis (Typical):** 60mV  
- **Output Type:** Open Collector  
- **Output Current (Sink):** 10mA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MC34164P-005 is designed to monitor power supply voltages and provide an output signal when the voltage drops below a preset threshold.  
- It is commonly used in power management applications to prevent system malfunctions due to low voltage conditions.  
- The device features an open-collector output, allowing it to interface with various logic levels.  

### **Features:**  
- **Precision Undervoltage Detection:** Ensures accurate monitoring of supply voltage.  
- **Low Quiescent Current:** Typically 75µA, minimizing power consumption.  
- **Wide Operating Voltage Range:** Suitable for a variety of applications from 1V to 24V.  
- **Built-in Hysteresis:** Prevents output oscillation near the threshold voltage.  
- **Open-Collector Output:** Compatible with different logic families.  
- **Robust Design:** Operates reliably across industrial temperature ranges.  

This information is strictly based on the manufacturer's datasheet for the MC34164P-005.
