Description and Introduction

Amplifiers and Comparators The MC34184 is a power supply supervisory circuit manufactured by Motorola (MOT). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MOT** (Motorola)  

### **Specifications:**  
- **Function:** Power supply monitor/supervisory IC  
- **Voltage Monitoring:** Monitors 5V power supplies  
- **Reset Threshold Accuracy:** ±1.5%  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Reset Output:** Active-low open-drain output  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MC34184 is designed to monitor power supply voltages in microprocessor and digital systems.  
- It ensures proper system operation by generating a reset signal if the supply voltage drops below a preset threshold.  
- The reset output remains active for a fixed delay after the supply voltage returns to a valid level.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Adjustable Reset Delay:** Configurable via an external capacitor.  
- **Open-Drain Output:** Allows flexibility in interfacing with different logic levels.  
- **Wide Operating Voltage Range:** Supports various supply voltages.  

This information is strictly based on the available knowledge base for the MC34184 from MOT (Motorola).
