Description and Introduction

HIGH AND LOW SIDE DRIVER The IRS21864PBF is a high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR).  

### **Manufacturer Specifications:**  
- **Manufacturer:** International Rectifier (IR)  
- **Part Number:** IRS21864PBF  
- **Type:** High and Low Side Driver  
- **Output Current:** 4.0A (source/sink)  
- **Voltage Range:** Up to 600V  
- **Propagation Delay:** 120ns (typical)  
- **Input Logic Compatibility:** CMOS/TTL  
- **Dead Time (Typical):** 540ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions and Features:**  
- **High Voltage Level Shifting:** Allows operation with high-side MOSFETs/IGBTs up to 600V.  
- **Independent High and Low Side Outputs:** Provides flexibility in driving both high and low side switches.  
- **Matched Propagation Delay:** Ensures minimal delay mismatch between high and low side outputs.  
- **Undervoltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Floating Channel Design:** Enables bootstrap operation for high-side driving.  
- **CMOS Schmitt-Triggered Inputs:** Enhances noise immunity.  
- **Cross-Conduction Prevention:** Built-in dead time to prevent shoot-through.  

The IRS21864PBF is commonly used in motor drives, power supplies, and other high-voltage switching applications.

Application Scenarios & Design Considerations

HIGH AND LOW SIDE DRIVER

Alternative Part Number

  • FAN7384MX --: High-side and low-side gate driver with similar 600V rating and drive capability, pin-compatible function in many half-bridge applications.
  • L6388ED013TR --: High-voltage half-bridge gate driver with comparable output current and bootstrap operation, suitable drop-in for many IRS2186 designs.
  • IR2113PBF --: Classic high-side/low-side gate driver from the same vendor family with similar voltage and current ratings, widely used as a functional substitute.
