Description and Introduction

Closed-Loop Brushless Motor Adapter The MC33039D is a monolithic integrated circuit manufactured by Motorola, designed for use with brushless DC motors. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Motorola  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 4.5V to 18V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current:** 20mA (sink/source)  
- **Input Frequency Range:** Up to 200kHz  

### **Descriptions:**  
- The MC33039D is a sensorless commutation controller for brushless DC motors.  
- It generates commutation signals by detecting back-EMF from the motor windings.  
- It is commonly used in conjunction with the MC33035 brushless DC motor controller.  

### **Features:**  
- **Back-EMF Sensing:** Detects motor position without Hall sensors.  
- **Phase-Locked Loop (PLL):** Ensures accurate motor synchronization.  
- **Adjustable Commutation Delay:** Allows fine-tuning of motor timing.  
- **Open-Collector Outputs:** Compatible with various driver stages.  
- **Low Power Consumption:** Suitable for battery-operated applications.  

This information is based solely on Motorola's documentation for the MC33039D.
