- **Package:** SOIC-8  

### **Descriptions:**  
The IR21094S is designed to drive high-side and low-side N-channel MOSFETs or IGBTs in a half-bridge configuration. It features high noise immunity and integrated dead-time control to prevent shoot-through.  

### **Features:**  
- **Floating Channel Design** for bootstrap operation  
- **Compatible with 3.3V, 5V, and 15V logic inputs**  
- **Undervoltage Lockout (UVLO)** for both channels  
- **Matched Propagation Delay** for both high and low sides  
- **Internal Dead-Time Control**  
- **Low Di/dt Gate Drive** for better noise immunity  
- **Pb-Free and RoHS Compliant**  

This driver is commonly used in motor control, power supplies, and inverter applications.
