Description and Introduction

POWER MANAGEMENT CONTROLLER The MC33128 is a microprocessor reset IC manufactured by Motorola (now part of ON Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Motorola (now ON Semiconductor)  

### **Specifications:**  
- **Function:** Microprocessor Reset Circuit  
- **Operating Voltage Range:** 2.7V to 24V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable via external capacitor (typically 200ms with 0.1µF)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin SOIC, 8-pin DIP  

### **Descriptions:**  
- The MC33128 is designed to monitor microprocessor power supply voltages and provide a reset signal when the voltage falls below a preset threshold.  
- It ensures proper system initialization by holding the microprocessor in reset until the supply voltage stabilizes.  
- The reset output remains active for a fixed delay after the supply voltage rises above the threshold.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Adjustable Reset Timeout:** Configurable via an external capacitor.  
- **Low Quiescent Current:** Typically 50µA, making it suitable for battery-powered applications.  
- **Wide Operating Voltage Range:** Supports systems from 2.7V to 24V.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Power-On Reset Delay:** Prevents false triggering during power-up.  

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