Description and Introduction

Half Bridge Driver, Soft Turn-On, Single Input Plus Shut-Down, Programmable 0.5-5us Deadtime in a 8-pin DIP package The IR21091 is a high-voltage, high-speed power MOSFET and IGBT driver from International Rectifier (IR).  

### **Manufacturer:**  
- **International Rectifier (IR)**  

### **Key Specifications:**  
- **High-Voltage Range:** Up to 600V  
- **Floating Channel Design:** Allows for independent high-side and low-side outputs  
- **Output Current:** Typically 290mA (source) / 600mA (sink)  
- **Propagation Delay:** Matched for high-side and low-side (typ. 120ns)  
- **Undervoltage Lockout (UVLO):** For both high-side and low-side drivers  
- **Operating Frequency:** Up to several hundred kHz  
- **Input Logic Compatibility:** TTL/CMOS compatible  
- **Supply Voltage (VCC):** 10V to 20V  
- **Deadtime Control:** Prevents shoot-through in half-bridge configurations  

### **Descriptions and Features:**  
- Designed for driving **N-channel MOSFETs and IGBTs** in half-bridge or full-bridge configurations.  
- **Floating high-side driver** enables bootstrap operation for high-voltage applications.  
- **Robust protection** with UVLO to prevent malfunction under low supply conditions.  
- **Matched propagation delays** ensure precise switching timing.  
- **Low power consumption** with CMOS input stages.  
- **Wide temperature range:** Suitable for industrial and automotive applications.
