Description and Introduction

TDA5145TS; Brushless DC motor drive circuit The TDA5145TS/C1 is a motor driver IC manufactured by PH (Philips Semiconductors, now NXP Semiconductors).  

### **Specifications:**  
- **Type:** Brushless DC Motor Driver  
- **Package:** SO24 (Small Outline 24-pin)  
- **Operating Voltage:** 10V to 30V  
- **Output Current:** Up to 1.5A (peak)  
- **Control Method:** Sensorless (back-EMF sensing)  
- **Commutation:** 120° block commutation  
- **Protection Features:** Overcurrent, undervoltage lockout, thermal shutdown  

### **Descriptions:**  
The TDA5145TS/C1 is designed for driving 3-phase brushless DC motors in sensorless applications. It integrates control logic, power drivers, and protection circuits, making it suitable for consumer and industrial motor control systems.  

### **Features:**  
- **Sensorless Operation:** Uses back-EMF zero-crossing detection for commutation.  
- **Integrated Power Drivers:** Includes six power MOSFET drivers for the motor phases.  
- **Speed Control:** Supports external PWM or analog speed control.  
- **Start-up Algorithm:** Built-in start-up sequence for reliable motor initiation.  
- **Protection Circuits:** Overcurrent, undervoltage, and thermal shutdown for safe operation.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official documentation.
