### **Descriptions:**  
- The IR21834 is a high-speed, high-voltage driver designed for driving power MOSFETs and IGBTs in half-bridge configurations.  
- It integrates independent high-side and low-side driver channels with matched propagation delays.  
- Features a floating high-side driver for bootstrap operation.  

### **Features:**  
- **Floating High-Side Driver:** Allows operation with bootstrap power supply.  
- **Matched Propagation Delays:** Ensures precise timing for high-side and low-side switching.  
- **Undervoltage Lockout (UVLO):** Protects against low supply voltage conditions.  
- **3.3 V, 5 V, and 15 V Logic Input Compatible:** Supports various control signals.  
- **Cross-Conduction Prevention:** Built-in dead time to prevent shoot-through.  
- **High Noise Immunity:** Robust against switching noise.
