Description and Introduction

DMOS DRIVER FOR BIPOLAR STEPPER MOTOR The part L6208 is a DMOS full bridge driver manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Current:** Up to 5.6A (peak)  
- **Operating Voltage:** 8V to 52V  
- **Logic Supply Voltage (VCC):** 5V to 7V  
- **RDS(ON) (per DMOS switch):** 0.3Ω (typical at 25°C)  
- **Switching Frequency:** Up to 100kHz  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** PowerSO20, Multiwatt15  

### **Descriptions:**  
- The L6208 is a DMOS dual full-bridge driver designed for motor control applications.  
- It integrates four DMOS power transistors in a full-bridge configuration, capable of driving bidirectional DC motors or stepper motors.  
- It includes built-in protection features such as thermal shutdown and non-dissipative overcurrent detection.  
- The device is compatible with logic-level inputs (TTL/CMOS) for easy interfacing with microcontrollers.  

### **Features:**  
- **High Efficiency:** Low RDS(ON) DMOS output stage reduces power dissipation.  
- **Integrated Protections:**  
  - Thermal shutdown  
  - Non-dissipative overcurrent detection  
  - Undervoltage lockout (UVLO)  
- **Cross-Conduction Prevention:** Built-in dead time to avoid shoot-through.  
- **Flexible Control:** Independent half-bridge control for PWM operation.  
- **Fast Decay Mode:** Improves motor braking performance.  

This information is strictly based on the manufacturer's datasheet for the L6208.
