Description and Introduction

TDA5140A; Brushless DC motor drive circuit The TDA5140AT/C1 is a motor driver IC manufactured by Philips (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Manufacturer:** Philips (NXP Semiconductors)  
- **Type:** Brushless DC Motor Driver  
- **Package:** SO20 (20-pin Small Outline package)  
- **Operating Voltage:** Typically 10V to 30V  
- **Output Current:** Up to 1.5A (peak)  
- **Control Method:** Sensorless commutation using back-EMF sensing  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**
- Designed for driving 3-phase brushless DC motors without Hall sensors.  
- Uses back-EMF zero-crossing detection for commutation timing.  
- Includes built-in protection features such as overcurrent and thermal shutdown.  
- Suitable for applications like fans, pumps, and small motor drives.  

### **Features:**
- **Sensorless Operation:** Eliminates the need for Hall sensors.  
- **Integrated Power Outputs:** Contains six power MOSFETs (three high-side, three low-side).  
- **PWM Speed Control:** Supports external PWM input for speed regulation.  
- **Protection Circuits:** Includes thermal shutdown, overcurrent protection, and undervoltage lockout.  
- **Standby Mode:** Low-power standby function for energy efficiency.  

This information is based on the datasheet and technical documentation for the TDA5140AT/C1. For precise details, always refer to the official datasheet from NXP (formerly Philips).
