Description and Introduction

MicroPower UnderVoltage Sensing Circuit The MC34164 is a voltage monitor IC manufactured by Motorola (MOTO). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 1.0V to 36V  
- **Threshold Voltage Accuracy:** ±2%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 10µA (typical)  
- **Output Type:** Open-collector  
- **Output Sink Current:** 10mA (minimum)  
- **Reset Delay Time:** Adjustable via external capacitor  

### **Descriptions:**  
- The MC34164 is a low-power undervoltage detection circuit designed to monitor system voltage levels.  
- It provides a reset signal when the supply voltage falls below a preset threshold, ensuring proper system initialization.  
- The device is commonly used in power supply supervision for microprocessors and other digital systems.  

### **Features:**  
- **Wide Operating Voltage Range:** Supports monitoring from 1.0V up to 36V.  
- **Precision Threshold:** ±2% accuracy for reliable voltage detection.  
- **Low Power Consumption:** Typically draws only 10µA of quiescent current.  
- **Adjustable Reset Delay:** Allows customization of the reset timing via an external capacitor.  
- **Open-Collector Output:** Compatible with various logic levels and easy to interface with other circuits.  
- **Robust Design:** Operates reliably across industrial temperature ranges (-40°C to +85°C).  

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