- **Package:** SO-16  

### **Descriptions:**  
- The L6585D is designed for driving MOSFETs or IGBTs in half-bridge configurations.  
- It integrates a high-voltage level shifter for the high-side driver and includes bootstrap diode functionality.  
- Features under-voltage lockout (UVLO) protection for both high-side and low-side drivers.  

### **Features:**  
- **High-Voltage Rail:** Up to 600V  
- **Bootstrap Diode:** Integrated for high-side drive  
- **UVLO Protection:** For both high-side and low-side  
- **Adjustable Dead Time:** Prevents shoot-through  
- **Low Power Consumption:** Optimized for efficiency  
- **Matched Propagation Delays:** Ensures precise switching  

This information is strictly based on the manufacturer's datasheet for the L6585D.

Application Scenarios & Design Considerations

Combo IC for PFC and ballast control

Alternative Part Number

  • TDA4863 --: PFC controller IC with similar function and pinout, widely used as a substitute in power factor correction circuits.
  • NCP1653 --: Compact PFC controller offering comparable performance and easy drop-in replacement in many designs.
  • UCC28070 --: Interleaved PFC controller that can replace the original in higher-power applications with minor circuit adjustments.
  • UBA2028T --: Integrated CFL ballast controller with similar half-bridge drive and PFC functionality, commonly used as a functional substitute for the L6585D in lighting ballast designs.
  • IRS2580D --: High-voltage half-bridge driver IC with comparable gate drive and protection features, suitable for replacing the L6585D in ballast and SMPS applications.
  • FAN7711 --: CFL ballast control IC offering similar oscillator, half-bridge drive and protection functions, providing a viable alternative when the L6585D is unavailable.
