Description and Introduction

Half Bridge Driver, Single Input Plus Inverting Shutdown Pin, Fixed 520ns Deadtime in a 8-Lead package The IRS2104 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. Below are the factual specifications, descriptions, and features based on the manufacturer's data:

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

### **Descriptions:**  
- The IRS2104 is a dual-channel driver IC designed for high-voltage, high-speed switching applications.  
- It is commonly used to drive both high-side and low-side N-channel power MOSFETs or IGBTs in half-bridge or full-bridge configurations.  
- It features a floating high-side driver capable of withstanding voltages up to 600V.  

### **Key Features:**  
1. **High-Side and Low-Side Drivers:**  
   - Independent high-side and low-side outputs.  
   - High-side driver can operate with a floating voltage up to **600V**.  

2. **Logic Input Compatibility:**  
   - Compatible with **3.3V, 5V, and 15V** logic levels.  

3. **Dead-Time Control:**  
   - Built-in dead-time to prevent shoot-through in half-bridge applications.  

4. **Output Current Capability:**  
   - **Peak Output Current:** ±210 mA (source/sink).  

5. **Propagation Delay:**  
   - Matched propagation delays for both high-side and low-side channels (~120 ns).  

6. **Undervoltage Lockout (UVLO):**  
   - UVLO protection for both high-side and low-side drivers.  

7. **Operating Voltage Range:**  
   - **VCC (Low-Side Supply):** 10V to 20V.  
   - **VB (High-Side Floating Supply):** 10V to 20V.  

8. **Switching Speed:**  
   - High switching speed with fast rise and fall times (~100 ns).  

9. **Temperature Range:**  
   - **Operating Temperature:** -40°C to +125°C.  

10. **Package:**  
    - Available in **8-pin PDIP and SOIC** packages.  

### **Applications:**  
- Motor drives  
- Switch-mode power supplies (SMPS)  
- Half-bridge and full-bridge inverters  
- Uninterruptible power supplies (UPS)  

This information is based on the manufacturer's datasheet for the IRS2104. For exact performance characteristics, refer to the official documentation.
