- **Rise/Fall Time:** 10ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** WSON-8 (SD)  

### **Descriptions:**  
The LM5109SD is a high-voltage gate driver designed for driving both high-side and low-side N-channel MOSFETs in half-bridge or synchronous buck configurations. It features a bootstrap diode for high-side drive and robust performance in high-frequency switching applications.

### **Features:**  
- **High-Voltage Operation:** Supports up to 100V  
- **Fast Switching:** Low propagation delay and rise/fall times  
- **Bootstrap Diode:** Integrated for high-side drive  
- **Wide Supply Range:** 8V to 14V for VDD  
- **High Peak Output Current:** 1.5A source, 2.5A sink  
- **Under-Voltage Lockout (UVLO):** Protection for both high-side and low-side drivers  
- **Small Package:** WSON-8 for space-constrained applications  

This information is strictly based on the manufacturer's datasheet and technical documentation.
