Description and Introduction

SMART CARD INTERFACE Here are the factual details about **Part L6605D** from the manufacturer **STMicroelectronics (ST)**:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Part Number:** L6605D  
- **Type:** Dual Full-Bridge Driver  
- **Operating Voltage Range:** 8V to 52V  
- **Output Current (Peak):** 2.5A (per channel)  
- **Logic Input Voltage:** 3.3V / 5V compatible  
- **Package:** SO-20 (Surface Mount)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Protection Features:** Undervoltage Lockout (UVLO), Overcurrent Protection (OCP), Thermal Shutdown  

### **Descriptions:**
- The **L6605D** is a **dual full-bridge driver** designed for driving inductive loads such as DC motors and stepper motors.  
- It integrates two independent H-bridge drivers with **PWM control** capability.  
- Suitable for **battery-powered applications** due to its wide operating voltage range.  

### **Features:**
- **Dual H-Bridge Configuration** (two independent full-bridge drivers).  
- **High Efficiency** with low RDS(on) MOSFETs.  
- **PWM Inputs** for speed and direction control.  
- **Cross-Conduction Prevention** (built-in dead time).  
- **Low Power Standby Mode** for reduced energy consumption.  
- **Fault Detection** (thermal shutdown and overcurrent protection).  

For exact electrical characteristics, refer to the **official STMicroelectronics datasheet**.
