Description and Introduction

DMOS DRIVER FOR THREE-PHASE BRUSHLESS DC MOTOR The L6229PD is a motor driver IC manufactured by STMicroelectronics (STM). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Current:** Up to 2.8A peak (1.4A RMS) per channel.  
- **Supply Voltage Range:** 8V to 52V.  
- **Operating Voltage (Logic):** 5V.  
- **RDS(ON) (Per Channel):** 0.3Ω (typical) at 25°C.  
- **Switching Frequency:** Up to 100kHz.  
- **Package:** PowerSO-36.  
- **Operating Temperature Range:** -40°C to +150°C.  

### **Descriptions:**  
- The L6229PD is a DMOS full-bridge driver designed for **DC motor control** applications.  
- It integrates **PWM current control** and **protection features**, making it suitable for industrial and automotive applications.  
- The device includes **four independent half-bridge drivers** with built-in shoot-through protection.  

### **Features:**  
- **Four Half-Bridge Outputs** (can be configured as two full bridges).  
- **Integrated Fast Freewheeling Diodes** for inductive load protection.  
- **PWM Current Control** with adjustable hysteresis.  
- **Undervoltage Lockout (UVLO)** and **Thermal Shutdown** protection.  
- **Cross-Conduction Prevention** (shoot-through protection).  
- **TTL/CMOS-Compatible Inputs** for easy interfacing with microcontrollers.  

The L6229PD is commonly used in **brushless DC (BLDC) motor drives, stepper motor control, and industrial automation systems**.
