Description and Introduction

SmartDRIVE HV Half Bridge driver with OP-AMP, smartSD, Comparator The L6390D is a high-voltage half-bridge gate driver manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 8V to 17V  
- **High-Side Floating Voltage (VB):** Up to 600V  
- **Output Current (Source/Sink):** 290mA / 600mA  
- **Propagation Delay:** 150ns (typical)  
- **Dead Time:** 1.2µs (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Descriptions:**
- The L6390D is designed to drive N-channel MOSFETs or IGBTs in half-bridge configurations.  
- It features a high-voltage level shifter for the high-side driver, enabling efficient switching in high-voltage applications.  
- The device includes under-voltage lockout (UVLO) protection for both high-side and low-side drivers.  

### **Features:**
- **High-Voltage Rail:** Supports up to 600V for high-side driving.  
- **Integrated Bootstrap Diode:** Simplifies circuit design.  
- **Matched Propagation Delays:** Ensures precise switching timing.  
- **UVLO Protection:** Prevents malfunction during low-voltage conditions.  
- **Cross-Conduction Prevention:** Built-in dead time to avoid shoot-through.  
- **Low Quiescent Current:** Enhances efficiency in standby mode.  

The L6390D is commonly used in motor control, power supplies, and inverters.
