Description and Introduction

PowerSPIN: DMOS driver for bipolar stepper motor The L6228Q is a motor driver IC manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Output Current:** Up to 2.8A peak (1.4A RMS)  
- **Operating Voltage:** 8V to 52V  
- **Logic Supply Voltage (VCC):** 5V to 7V  
- **RDS(ON) (per DMOS):** 0.3Ω (typical at 25°C)  
- **PWM Operating Frequency:** Up to 100kHz  
- **Protection Features:** Overcurrent, Thermal Shutdown, Undervoltage Lockout (UVLO)  
- **Package:** PowerSO-36  

### **Descriptions:**  
- The L6228Q is a DMOS full-bridge motor driver designed for high-efficiency motion control applications.  
- It integrates a dual monolithic DMOS bridge with a mixed-signal control circuit, enabling precise motor control.  
- Suitable for driving brushed DC motors, stepper motors, and other inductive loads.  

### **Features:**  
- **High Efficiency:** Low RDS(ON) DMOS output stages reduce power dissipation.  
- **Flexible Control:** Supports PWM current control with adjustable off-time.  
- **Integrated Protection:** Includes thermal shutdown, overcurrent protection, and cross-conduction prevention.  
- **Wide Voltage Range:** Operates from 8V to 52V, making it suitable for various industrial and automotive applications.  
- **Diagnostic Output:** Provides fault indication for system monitoring.
