Description and Introduction

CFL/TL BALLAST DRIVER PREHEAT AND DIMMING The L6574D is a high-voltage half-bridge driver manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage (VCC):** 8.5V to 15V  
- **High-Side Driver Voltage (VB):** Up to 600V  
- **Output Current (Source/Sink):** 350mA / 650mA  
- **Propagation Delay (Typical):** 120ns  
- **Operating Frequency:** Up to several hundred kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-16  

### **Descriptions:**
- The L6574D is designed for driving MOSFETs or IGBTs in half-bridge configurations.  
- It includes a high-voltage level shifter for the high-side driver, enabling efficient switching in applications like motor drives, power supplies, and lighting.  
- Features built-in dead-time control to prevent shoot-through in the half-bridge.  

### **Features:**
- **High-Voltage Rail:** Supports up to 600V for high-side driving.  
- **Undervoltage Lockout (UVLO):** Protects against low supply voltage conditions.  
- **Interlocking Function:** Prevents simultaneous conduction of high-side and low-side switches.  
- **Matched Propagation Delays:** Ensures balanced switching performance.  
- **Low Quiescent Current:** Optimized for energy efficiency.
